I'd have thought that the fire retardants would be more environmentally friendly, that is, would degrade with time - otherwise we'd have a bunch of orange-painted trees out there, no? Does anybody know more of the story behind this? Just curious...

The four days of 15+hr hiking was really pushing the limit and only very few people even attempted the hard peaks such as McGee, Charybdis, Marion, Deerhorn. Everyone else was looking for easier alternatives.

I'd heard that a plane dumped a load of fire-retardant across the summit sometime in the past, but thought that might be more fiction than truth. Upon closer examination, one can see that indeed something was spilled on the rock that doesn't wash off:

Newer retardants use ammonium sulfate or ammonium polyphosphate with attapulgite clay thickener or diammonium phosphate with a guar gum derivative thickener. These are not only less toxic but act as fertilizers to help the regrowth of plants after the fire. Fire retardants often contain wetting agents, preservatives and rust inhibitors and are colored red with ferric oxide or fugitive color to mark where they have been dropped. Brand names of fire retardants for aerial application include Fire-Trol and Phos-Chek.
Some water-dropping aircraft carry tanks of a guar gum derivative to thicken the water and reduce runoff.
