Thunderhead over Jack Lake

Jack Lake in the Central Oregon Cascades is at one of the trailheads leading into the Mount Jefferson Wilderness.  It’s a beautiful alpine lake with plenty of mosquitoes in early summer.  I usually put off my trips into the backcounty until after first frost in the fall, mainly to avoid the bugs (people are less numerous too).  The thunderhead in the photo spawned a full-fledged rain and hail storm.  We were on the trail about a mile from the car when the storm hit.  I buried my camera deep in my pack to keep it dry.  Lesson learned: carry a couple of Ziploc plastic bags for camera gear when on the trail.
