Field Notes

Description:

Cryptobiotic soil crusts, consisting of soil cyanobacteria, lichens and mosses, play an important ecological roles in the arid Southwest. In the cold deserts of the Colorado Plateau region (parts of Utah, Arizona Colorado, and New Mexico), these crusts are extraordinarily well-developed, often representing over 70 percent of the living ground cover.
Cryptobiotic crusts increase the stability of otherwise easily eroded soils, increase water infiltration in regions that receive little precipitation, and increase fertility in soils often limited in essential nutrients such as nitrogen and carbon

Notes:

This soil is so fragile and so much a part of the southwest. When you hike into remote areas where the soils havent been disturbed the cryptobiotc soil can be a foot deep representing thousands of years of growth

I'm in Eastern Utah, out in the desert area. Thank you for answering my questions it's much appreciated. :)
I am in Sandy - we are very soggy at the moment! Actually just got hail. Not sure where you are Bryclover but the area I took this photo is pretty dry - no flooding there except in from snow melt. My guess is that the soil wont grow in areas where flooding could cause erosion. So down in Escalante for example the c.soils are not in the gullies or washes or on the sides of hills. I havent seen this soil near river beds either.
The weather in utah now has had a lot of flooding especially out in the desert where I'm at.
When you live in the desert you learn early that it is fragile and not to be disturbed. Not sure about extreme rainfall since it exists in an area with little rainfall. What do you consider extreme?
I see this around and I was told not to step on it, but I was wondering how it handles extreme rainfall. Any ideas?
