Went up late Friday and spent the night in Bluff Spring. The water is starting to dry up and I'd estimate it won't last another week or so. Went on Dutchman north around to Terrapin then back on Bluff Spring to the trail head. My GPS measured 15.6mi. All along the trail the juvenal poppy's are covering either side for a lot of it. Give it two weeks and the place will explode with blooms.
