Mojave National Preserve 2003

James contemplates handholds for a climb. It doesn't seem that volcanic rock is conducive to climbing.

The top of the cave shows a smorgasbord of melt.

Shortly up the tube is what appears to be a mine shaft. Perhaps it was an air tunnel?

A swollen red yucca bloom.

Hiking a bit further up the hills by the tube, I happened upon a depression of sand and Joshua Trees. It struck me that this was an "anti-oasis."

Black Tank probably has a lot of water at certain times of the year. There are trenches that bring the area run-off to it.
