Landscapes and Landforms of the Okanogan Highlands
Everywhere you look in the Okanogan Highlands you can see evidence of the movement of glaciers. The trick is knowing what to look for! On March 6, CWU geography professor Karl Lillquist used local landscapes and landforms to demonstrate how glaciers and other factors shaped our region during the last glaciation in our area, 12,000-18,000 years ago.
Okanogan Highlands Alliance (OHA) and Okanogan Land Trust (OLT) are excited to be co-hosting three-part series of educational events focused on geology. OHA hosted the first event on Friday, March 6th, when Dr. Karl Lillquist returned to Tonasket for the Highland Wonders presentation. OLT will host the second event at some point in the future, but it has been postponed to protect public health. When we are able to resume public events, Bruce Bjornstad will present as part of the OkaKnowledgy lecture series in Okanogan. The third event, also led by Dr. Lillquist, will take participants on a field trip in the Highlands, hopefully this summer! All three events will highlight the fascinating geological processes shaping our hills and valleys. The indoor events are free and open to all; the field trip will require pre-registration with priority given to OHA and OLT members. Anyone can become a member!
Friday, March 6, Community Cultural Center of Tonasket:
Dr. Lillquist led the audience in “explor[ing] the origins and evolution of landscapes and landforms in the Okanogan Highlands.” He described how the Okanogan Highlands landscape has been sculpted over time by glaciers and other forces. Specifically, he explained how “The Okanogan Highlands, [which is] characterized by rolling uplands, punctuated by a diverse array of valleys…has been shaped by various tectonic, weathering, landslide, stream, glacier, and wind-related processes.“
Dr. Lillquist is a professor in the Geography Department at Central Washington University, and has vast experience exploring and teaching about the geology of our state. His area of expertise is geomorphology, a field focusing on landforms and how they originated. Throughout our three-part series, we hope that you will join us in looking at the Highlands landscape through geologic time — you might never look at our highland hills and valleys the same way again!
Highland Wonders events feature the natural history of the Okanogan Highlands and surrounding areas. OHA offers educational programming on the first Friday of the month from November through April. The presentations, which start at 6:30 pm, are free to the public (donations are welcome), and clock hours are available for educators. The events take place at the Tonasket Community Cultural Center, and dinner is available before the presentations. (meat and vegetarian options available, $10 a plate).
