This photo of the Wyoming State Flower, “Indian Paint Brush”, was taken on a 70F+ day I was in shorts and t-shirt, but a heavy storm with lightning came roaring in, temperature dropped from 70 to 20 in minutes and then of course the rain turned to snow and then all “hail” broke loose!  However, I like weather, I watch it incessantly, I see which way the clouds are moving and how fast and remember it. So, I just made for cover at a pace that would get us there before the storm hit. Tango and I hid safe & dry under a forest canopy for about 30 minutes until it calmed down, then became a sunny day again.  Staying dry is primary to staying warm, in a place like this with such extreme temperature swings, it's a matter of life and death. I have been waterskiing in July on Jackson Lake and been snowed on! Never go out without provisions for warmth. Indian Paint brush flowers come in many shades and hues of red. The Hoback Canyon has the largest flowers and Upper Flat Creek has fluorescent red colors. Indians wisely didn’t live in Jackson Hole because the weather was highly unpredictable and so very deadly. Most of the time, they were in Dubois WY or Idaho.
