Did some hiking in the Wichita Mountains this weekend, only about 45 minutes from Altus, and a few of the only "mountains" in Southwest Oklahoma. Searched for a cave, but never found it. And the weather was rather dismal (and cold), which made for difficult photographing.
Lots of bouldering to get around.
Also got to see some bison, which was pretty neat. Until one stared me down... then I bounced.
Click on the pictures or go the Oklahoma album to see a couple more.
