Desert Sky in Autumn

While camping at Red Rock Canyon in California's Mojave Desert last night, I noticed some clouds moving in from the west just at sunset. I had assumed they would ruin my plans to take a photo of the Milky Way setting over the red rocks of the desert badlands so I shot this as close to the end of astronomical twilight as possible, perhaps even catching the end of twilight. Soon after, the clouds moved in completely, and today it's raining there.
