I hit this hike on the perfect day for palo verde. Big yellow puffballs dotted the subdivisions below. So very pretty. This was April 15, 2018

A lot of the creosote was also in bloom (creosote blooms more according to rain than season):
A few of the staghorn or buckhorn cholla were putting on a show:
And then there were the chuckwallas. I saw three on that hike, literally doubling my lifetime sightings. The first picture is a tiny one:
And here is a bigger one hiding in a crevice (as they're wont to do):
And this lovely hummingbird. What a great day.
