By Paul Carter – July 2020

In June 2020 I took three one-night trips to the Big Bear Lake area in the San Bernardino Mountains east of Los Angeles; spending about 3 hours each night looking for Humboldt’s Flying Squirrel (Glaucomys oregonensis), seen on the Castle Rock Trail. The trip list of 15+ mammals included a Black Bear with three cubs seen on Skyline Drive.
