Yellow-pine chipmunk records trace Oregon’s volcanic Cascades from Mount Hood and Deschutes National Forest south through Newberry to Crater Lake. The reporting season is tightly concentrated from June through September, with no records in January, February, November, or December in this series. That seasonal gap reflects observation opportunities as well as animal activity, and the records do not measure chipmunk abundance.
