After being chased out by an oncoming storm on a quick hike from the Toadstools trail I headed east to camp for the night at Lone Rock beach along Lake Powell in Utah.

The stormy sky made for a great sunset over Lone Rock.

And a great sunrise too.
It sprinkled most of the night. I know because I was awake not able to sleep on the deflated air mattress.

Looking east towards Page Arizona
The beach was crowded for a week night.

I had concerns with the possibility of hard rain cancelling my tour of Antelope Slot Canyon, not the place to be in a possible flash flood. 
What tours or activities have you had to cancel because of weather conditions?
