Oregon pika records trace high, rocky country along the Cascades, from Mount Hood and Willamette national forests south to Crater Lake, with additional coverage east of the crest in Deschutes. Observations are overwhelmingly a summer phenomenon: July through September dominate, while January and February have none in the monthly series. Those records reveal the timing and location of detection in accessible talus, not pika abundance, and sparse winter reporting should not be mistaken for seasonal absence.
