If You Were A Tree
Imagine that you are a tree looking for a new home on the High Plains. You might come across this job posting:

Main duties include sheltering homes and livestock from wind and searing sunlight, holding soil in place, and providing shelter for wildlife. Beauty in the way of nice foliage, flowers, or fruit are a plus.
Could You Survive?
Drought: Cheyenne gets about 16 inches of rain every year, but received less than six inches in 1964. There have been streaks as long as 56 days with no precipitation.
Growing Season: On average, Cheyenne is frost free between May 20 and September 20, but the temperature has dipped below 32°F in every month except July and August.
Temperature: The record low is -34°F; the record high is 100°F. The temperature in Cheyenne dropped from 43°F to 3°F in just 30 minutes on December 21, 2022.
Winds: The average wind speed in Cheyenne is 13 mph. Wind speeds greater than 80 mph are not unusual.
Sunlight: Cheyenne is sunny 250 days of each year, on average. Because of the high elevation, the sun is as intense here as it is in desert cities further south, such as Las Vegas, NV.
Humidity: Relative humidity may be as low as 5%, and the high elevation means water evaporates more quickly.
If you were a tree, would you be able to survive here?
