Collections Close-Up: Making Sense of Made-for-Sale

Walking down the collection’s basketry aisle, drinking in the breathtaking variety of shape, texture, and technique, a glint might catch your eye. Amongst the warm sheen of stripped willow shoot or the bright yellow of dyed porcupine quill, you might catch the unmistakable sparkle of glass. It might surprise you to find such a material on the basketry shelves. Last month we talked about how the spooky or the scary can spark learning opportunities, here at SCMNH we also seek to unpack surprises. Following that course, this month we will be digging deeper into one of the wonders of our basketry collections: a  “made for sale” basket.

Following this sparkling glass to its source, you would find a bottle-shaped basket, twined in warm browns and light yellows. The red-brown was likely from tule root, the yellow from tule or cattail leaves, and the black accent, dyed tule. The alternating stripes of color end in an attached coaster-like platform. Taking a closer look, you would discover that the shape arises from the glass bottle it overlays. The basket was collected in Northern California and is attributed to the Klamath River tribes. Today’s federally recognized Klamath River tribes are composed of the Klamaths, Modoc and Yahooskin, distinct peoples whose basketry traditions have similarities.

The absence of specific information about the basket’s weaver is contrasted by our knowledge of the collector. Maude Silvey was already a longtime resident of Santa Cruz by 1970, when she donated her personal collection of more than one hundred baskets to the great joy of museum staff and community. News articles of the time reflect the extent of her interest in baskets, where we learn that “Mrs. Silvey had visited northern California Indian tribes to observe weaving techniques and to obtain baskets for the collection.”

Her story unfolds against the broader backdrop of collecting trends at the time. Born in the 1880s, Maude Silvey’s early years coincided with the raging temperature of America’s “canastromania” or basket fever. Coined in 1904 by Smithsonian curator Otis Mason, this frenzied collection of baskets swept American culture from about 1890 to 1920. It was spurred by several factors; from the leisure time of an emerging middle class that was being lured west by railroads to the notion that baskets were primitive but pristine objects made by a doomed race that needed to be salvaged.  (For an incredible discussion of these interwoven complexities, check out Basket Weavers for the California Curio Trade, a book exploring the lives of Elizabeth and Louise Hickox, weavers from the Klamath River area). 

Many well-known collections of California basketry were developed around this time, including that of the Hearst Museum of Anthropology. It was their Lawrence Dawson who helped identify and describe baskets in our own collection in the late seventies. A significant percentage of which were described as “made for sale”. 

It seems like a straightforward term at first, applied to baskets made for commercial consumption, like the ones collected on Mrs. Silvey’s trip. Probing the meaning of this category, we might ask how such trips were planned, how the weavers were compensated, and how they emphasized traditional techniques or innovated with them. Early 20th century museums tended to deliberately obscure these kinds of commercial exchanges in their interpretations or avoid displaying baskets that diverged from anthropological understandings of tradition, treating indigenous weavers as if they were confined to the past rather than living craftspersons. 

In examining these aspects of our collection, we find that our “made for sale” baskets fit two main types. Some baskets take traditional (a complex term itself, which we might also phrase as “in the style of objects made pre-contact”) forms and functions, and appear to have been sold to collectors unused. An example of these is a cooking basket with neither food residue nor burns from cooking stones. 

The other type, which includes the bottle baskets, have forms or functions that are innovations from tradition. Traditional water carrying baskets in California Indian basketry would have relied on watertight weaving and some kind of sealant, rather than a glass center. Other baskets in our collection that follow this type include a tiered hanging shelf, a wall hanging plaque with a holding pouch, and others.


As National Native American Heritage Month, November is an opportunity for institutions to pay deliberate attention to the history and continuing culture of America’s indigenous peoples. Unpacking the words we use to describe the objects in our collections, especially across cultural differences and within the context of colonialism, is a critical component of good stewardship. To delve further into our basketry collections and the forces that shape them, check out this month’s Collections Close Up event on November 12th.

Rock Record: Caverns of Time

By Gavin Piccione and Graham Edwards

Caves are an intersection between natural destruction and creation, where existing rocks are eroded away, and new rocks are continuously formed. Descend into one of the many caves in Santa Cruz and you’ll get a unique viewpoint of the striped marble walls that were built offshore of the area’s ancient shorelines and thrust up onto the continent over the past million years.

This geologic flux also means that one can never enter the same cave twice, since the competing geologic processes of erosion and precipitation are constantly shaping the interior. When you visit a cave, you’ll be a first-hand witness to the geologic processes that shape the Earth.

Gavin and Graham explore speleological features in Empire Cave on the UCSC campus.

Solutional Caves and Karst

The caves of Santa Cruz are called solutional caves because they form when groundwater dissolves pathways through rock, just as sugar or salt dissolve in warm water. However, to dissolve rock, it takes more than just plain old water. Rainwater and groundwater carry dissolved carbonic acid and organic acids that are pulled out of the soil as water percolates down from the surface. In Santa Cruz the bedrock (the solid rock beneath the soil) is mostly marble and made of the mineral calcite which is very susceptible to being dissolved by weak acids like these. Thus, the slightly acidic water can easily dissolve its way into the rock.

You can try this at home or in the field! Find a piece of marble or limestone, scratch at the surface a little bit with a paperclip, key, or coin to make a powder. Drip some vinegar (which is also a weak acid) on the powder and watch it fizz as the calcite dissolves!

As rainwater and groundwater slowly dissolve their way through the marble bedrock over thousands to millions of years little cracks turn into large caves, where the many dissolved minerals such as calcite precipitate, or become solid and separate out of the liquid, forming speleothems. These water-sculpted caves have a distinctive structure and shape: smoothed and rounded marble walls filled with holes and tunnels, covered with speleothems giving most surfaces a ropey, grooved, and nodular texture. In karst systems caves can develop as we’ve described, but if they grow close enough to the surface, the caves can’t support the weight of overlying rock and they collapse forming sinkholes, a familiar feature in the Santa Cruz area.

Since karst caves are formed by flowing water, water often continues to flow into them. Especially in the rainy wintertime, caves can partially or completely fill with water, so it’s important to be very careful whenever entering or exploring caves and postpone your spelunking if it’s rainy!

Below the Surface

One of the most scientifically alluring aspects of caves are the preservation of rocks and artifacts that their sheltered interiors provide. Materials within caves are not subject to erosion or weathering to the extent that those exposed to the atmosphere are. Caves also stay the same temperature year-round because they are not affected by atmospheric temperature fluctuation, and instead have temperatures regulated by the ability of the surrounding rock to hold heat. These mild conditions help artifacts like the Dead Sea scrolls and cave paintings to survive for millennia. Similar to archeological preservation, rocks that would normally erode quickly at the surface of the Earth are remarkably well preserved in caves.

Caves are treasure troves of samples for geologists, biologists, hydrologists, and countless other kinds of scientists. Among the most exciting (at least for us geochronologists) are records of changing climate found in speleothems. As this calcite builds thicker and thicker speleothems, it captures the chemical signature of the climate at the time of its formation. By studying these speleothems, scientists can reconstruct the timeline of global climate change over the past 650,000 years.

Other Types of Caves

Some caves form at the same moment the rock forms, usually from cooling lava. Some examples of these volcanic caves are lava tubes — an open tunnel left behind when a subterranean conduit of lava drains. Caves can also form in the deep chasms left behind by rifts, where volcanoes split the land apart as they swell. Since lava flows, volcanoes can leave all sorts of other cave-like voids behind from the flow, storage, or drainage of lava.

Sea caves, or littoral caves, form where waves carve out deep caverns into sea cliffs, usually into weaker parts of rock. We even see a few shallow sea caves along the Santa Cruz coastline!

Anchialine caves are caverns that connect inland pools, called anchialine pools, to the ocean where the cave ends underwater. The water levels in these pools often rise and fall with the tides, and these are popular sites for scuba-spelunking!

Caves can even form above ground! Talus caves form in the spaces between large boulders at the base of rocky cliffs, and if water flows into or under a glacier, it can melt out glacial caves!


Critters in Caves

While we most often associate caves with bats, caves are home to all sorts of organisms, including fungi, arthropods (insects, spiders, scorpions, and the like), salamanders, and fish. These creatures are usually adapted to live in these perennially dark, often flooded environments. Because caves are often isolated and disconnected habitats, many creatures that live in caves are endemic, meaning they are found in that cave network and nowhere else on Earth!

For example, the Cave Gulch cave network, just North of Santa Cruz, is home to two endemic species: the spider Meta dolloff and the pseudoscorpion Fissilicreagris imperialis.

Be very conscientious when you visit caves since these are the only homes for many of the creatures that live there. Never leave trash, burn fires, or damage the interiors of caves. If you do go into caves, be sure to pack trash out, or even better, enjoy the cave from the outside and leave its subterranean residents in peace.

On the Rocks: Foraged Liqueur

This recipe is part of our series On the Rocks: Exploring Science and Nature through Curated Cocktails.

During summer months and into early fall, California’s native berry-producing plants provide humans and wildlife alike with a delicious source of nutrients.

[Gathering fruit] required an intimate familiarity with nature and natural patterns. … Indians watched the other animals and linked their behaviors with the ripening of the fruit. Goldfinches, for example, would begin to whistle more frequently when it was time for the Foothills Yokuts to gather blackberries. Keeping a close watch on weather patterns was also important. For example, rosehips…tasted sweetest after the first light frost or cold nights of fall. The Karuk harvested California huckleberries after the first frost because that was when they were sweetest.

Tending the Wild: Native American Knowledge and the Management of California’s Natural Resources by Kat Anderson, 2005

While there are many edible uses for our native berry varieties, a few species are particularly useful for making liqueurs to add a little local flavor to your cocktail game. Our favorites are California blackberry (Rubus ursinus), pink flowering currant (Ribes sanguineum), and blue elderberry (Sambucus nigra ssp. cerulea). Explore our foraging guide before you go out on the hunt and then try your hand at making your own liqueur with our recipe (below).

Foraging Ethics

Before you forage from natural landscapes, it’s important to Know Before You Go. Research the rules and regulations for the landscapes you hope to explore, study the species you may find, and be prepared to identify them accurately. Once you identify the species you would like to forage and you are confident that you are legally allowed to, consider how to do so in a way that does not cause harm. Only take what you will use and leave enough for wildlife.

Biologist of Potawatomi heritage Robin Wall Kimmerer provides an excellent blueprint for ethical foraging based on the indigenous principles of the Honorable Harvest:

Know the ways of the ones who take care of you, so that you may take care of them.
Introduce yourself. Be accountable as the one who comes asking for life. Ask permission before taking. Abide by the answer.
Never take the first. Never take the last. Take only what you need.
Use it respectfully. Never waste what you have taken. Share.
Give thanks for what you have been given.
Give a gift, in reciprocity for what you have taken.
Sustain the ones who sustain you and the earth will last forever.

Make a Macabre Martini with your liqueur!

On the Rocks: The Macabre Martini

This recipe is part of our series On the Rocks: Exploring Science and Nature through Curated Cocktails.

In works of art, macabre refers to a grim or ghastly atmosphere. At the Santa Cruz Museum of Natural History, it heralds a season of oddities — when we turn our attention to the nooks and crannies of nature, looking for the strange, the puzzling, and the disturbing.

In honor of our annual event of creatures, curiosities, and cocktails, Museum of the Macabre, we’re mixing things up with a special concoction to give you pause — and we mean that! This cocktail requires some toil and trouble, but it’s well worth it in the end.

The Macabre Martini is a mysterious mixture, obscured by the darkness of a homemade sesame syrup. Another way to reach this deep black color is with activated charcoal, though you should look into the risks if you are on any medications.

Looking to add a little local flora to your cup? Substitute the crème de mûre with a homemade blackberry, elderberry, or black currant liqueur.

Ingredients

Macabre Martini:

  • 1 oz gin
  • 2 oz crème de mûre (or homemade berry liqueur)
  • 2 oz black sesame syrup (see below for instructions)
  • 1 oz lime juice
  • 1 large egg white
  • Blackberries for garnish

Black sesame syrup:

  • 1 cup black sesame seeds
  • 3/4 cup sugar
  • 1/2 cup water (or more as needed)
  • zest of half a lime
  • 2 oz vodka

Instructions

To make the black sesame syrup:

  1. Toast the black sesame seeds in a saucepan over medium heat for about 2 minutes while constantly moving them around in the pan. Remove from heat and allow to cool.
  2. Blend the seeds in a food processor, coffee grinder, or blender until they are a powder and set aside.
  3. Put the sugar, water, and lime zest in a small saucepan and bring to a low simmer, stirring until the sugar has dissolved. 
  4. Add the black sesame seed powder and bring to a boil. Let bubble for 2 minutes. 
  5. Remove from the heat and leave to cool completely.
  6. Strain through a fine mesh sieve, and then again through cheesecloth, so you have a smooth and thick syrup. This is the trickiest part!
  7. Stir in the vodka. It will keep in the fridge for up to three months, so feel free to make this part in advance.

To make the Macabre Martini:

  1. Line the rim of a martini glass with leftover sesame seeds by first running a lime wedge around the edge and then dunking the edge in the seeds.
  2. Put all the cocktail ingredients in a shaker and shake vigorously for 60 seconds.
  3. Add three ice cubes, and shake again for 30 seconds or until cocktail feels cold through the shaker. 
  4. Strain into a martini glass.

Collections Close-Up: Storytelling with Skulls

This month’s Collections Close Up stares out at us from the intersection of spooky, stunning, and scientific – of storytelling with skulls. To set the scene, we introduce a newer member of the Museum’s collection – the skull of a turkey vulture (Cathartes aura), part of a complete skeleton given to the museum from the collection of Ray Bandar. 

These birds are no stranger to Halloween-esque themes – carrion eaters like turkey vultures feed on the decaying flesh of dead animals. While this is exactly as spooky as it sounds, it’s also an essential ecological role. By consuming dead animals, turkey vultures and other carrion eaters help reduce the amount of disease in the ecosystem. 

It’s also this very behavior that has inspired the term vulture culture – an evolving subculture of people who are captivated by the artistic allure of body parts of dead animals. Of course, there’s more to a skull then how nicely it would cover part of your wall. From a science education perspective, skulls tell stories of the adaptations that animals use to survive in the world around them. For example, here we note a strong, sharp beak for tearing meat from bones rather than sipping nectar from flowers or straining food from water. Researchers dig deeper into the morphology, or structures of skulls, looking at hundreds of individuals bones to build our understanding of animals’ lives.

Collector Ray Bandar, was no stranger to balancing a morbid fascination of skeletons with their scientific and educational value. So driven by his passion to study nature’s “sculptures”, the humble Bay Area high school teacher spent 60 years as a field associate for the California Academy of Sciences (CAS). While his collection contained everything from birds to bears, his particular speciality was marine mammal skulls. Working in collaboration with Academy scientists and the West Coast Marine Mammal Stranding Network efforts, Bandar spent decades oncall for collecting trips from Bodega Bay to Año Nuevo.

Day or night, whenever the calls came, the first part of the process for deceased animals was also the most important: collecting the data. Information such as the location, species, sex, size, apparent cause of death are critical for a specimen’s contribution to science. He would often participate in the entire messy, squishy and smelly process of taking these animals from “From Death to Display”.

Skulls are collected because they are information-rich – scientists can learn a lot from the wear on the teeth to the size of the brain case and more. They are also expedient – it is easier to store the skull of a whale than an entire individual. Nonetheless, in rare or scientifically valuable cases, like Orca O319 – scientists may take the whole animal.

Whether whole or in pieces, Bandar contributed thousands of specimens to Cal Academy’s collections, particularly California sea lion skulls. Collected under CAS permits, many of the specimens were stored in his home, or “Bone Palace”. A stunning take on the palatial, specimen rich displays of natural history collections throughout time, Bandar’s labor of love inspired numerous articles and even a documentary or two.

Never the shy collector, Ray was also a constant public fixture at the Academy. He designed exhibits, wrote labels and staffed events, particularly around Halloween. Today, elements of his collection are still on display, supporting the CAS’s stories of skulls.  

After Ray’s death in 2017, well documented members of his skeletal menagerie were relocated to Academy collections storage. The folks at the Academy generously shared the remaining wealth of Bandar’s kingdom with science education organizations – including your local natural history museum. Thrilled to take part in the rich legacy of “Bones” Bandar, Museum staff collaborated to select a set of specimens to flesh out the gaps in our collection, focusing on enhancing our capacity to engage visitors with the striking elements of the natural world. 

And that has been the case for this turkey vulture skull – whose first public debut was as a creepy carrion eater with an ecological heart of gold for 2019’s “The Birds” themed Museum of the Macabre. Other Bandar specimens, including a second turkey vulture skull, showcased biodiversity – enriching our “exploded bird” exhibit case. 

Macabre has traditionally been our evening of curiosities, creatures, and cocktails – where we dig into the seemingly strange or ostensibly awful elements of the natural world to create space for different kinds of connections. Join us this year for online events, whether for creepy caves, macabre mushrooms, taxidermy tips or a deeper dive into cabinets of curiosities and their relationship to modern museums.
