Naturalist Night: Coastal Prairies

California’s Coastal Prairies are a rare and incredibly biodiverse habitat found in Santa Cruz, and the most species-rich grassland type in North America. Despite its rarity and species-richness, this is a habitat-type at risk of continued range loss due to development, fire suppression, invasive plants, and other factors. During this interactive class we will explore these threats to this habitat type, as well as what makes coastal prairies unique, including the geology of coastal terraces, notable species, and ecological factors that have impacted the habitat type over millennia, including cultural burning by indigenous communities.

We are also excited to have a special guest join us this time! Justin Luong is a Ph.D. researcher in Environmental Studies at UC Santa Cruz, currently focused on grassland restoration in California, and will share his research regarding potential impacts on coastal prairies due to climate change and drought.

About the series: Join fellow nature enthusiasts for monthly explorations of the biodiversity of Santa Cruz County. Each month, our Public Programs Manager Marisa Gomez will share the stories of a specific Santa Cruz habitat as we develop our skills as naturalists.

This series will feature a presentation as well as an interactive session and is in partnership with Santa Cruz Public Libraries. Come prepared to share and to learn alongside naturalists deep in their journey and just starting out.

Collections Close-Up: The Interwoven History of Baskets and Museums

Ohlone Basket

Spend an evening unraveling the complex ways in which consumer trends and museums influenced early 20th basketry collections and craft. Collections Manager Kathleen Aston will elaborate on these trends and how they relate to our collection. Joining us will be Julie Sidel, Interpreter 1 for Santa Cruz Mission State Historic Park, to share how the intersection of museum artifacts and interpretation illuminates daily life at the Santa Cruz Mission.

About the series: Zoom into the stories, secrets, and science of our collections during monthly webinars with Collections Manager Kathleen Aston. This live event is an extension of our monthly Collections Close-Up blog, with added insights and intrigue. Members are invited to participate in this program before it is made available to the general public as well as ask questions directly of Kathleen.

There have been a dozen major and minor supercontinents over the earth’s 4.567 billion year history, and odds are that there will be more. Explore plate tectonics and continental drift in this month’s Rockin’ Pop-Up.

About the Series: Join the Geology Gents, Gavin and Graham, for monthly conversations about rocks live on Facebook. Each month we’ll explore a different geologic topic, from Santa Cruz formations to tips for being a more effective rockhound. Graham Edwards and Gavin Piccione are PhD candidates in geochronology with the Department of Earth and Planetary Sciences at UC Santa Cruz.

Submit your questions ahead of time by emailing events@santacruzmuseum.org and feel free to include pictures of rocks you’d like identified! Pro-tip: the better the picture, the better the ID.

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.
