The complete county distribution, spread across 28 Oregon counties. Every occurrence record falls in one county, so these sum to the total. Counties from GBIF and US Census boundaries.

Golden-mantled ground squirrel records form a Cascade corridor through Crater Lake National Park and Deschutes and Mount Hood national forests. Nearly all documentation falls in the active season, rising sharply in spring and concentrating from June through September, with very few winter reports. That seasonality affects detectability, so the record map is not an abundance map.
