[Geysers] Strange feature

[TSBryan at aol.com]

For some reason -- probably has to do with being "stuck" in southern  
Arizona for another three months -- I was using Google Earth to look at  places 
in Yellowstone. For some reason (no idea why, really) I zoomed in on the  
Spruce Creek-Juniper Creek area, a few miles up Nez Perce Creek well beyond the 
 Morning Mist area.
 
First, here is what Allen & Day (pp. 283-284) had to say about that  area:
 
     The southern branch of Nez Perce Creek is formed  by the junction of 
Spruce and Juniper Creeks, cold mountain streams which  receive no warm water 
till they near the meadow where they unite. Three-quarters  of a mile up 
Spruce Creek, the explorer comes upon an old sheet of siliceous  sinter, along 
the western border of which a mild type of acid activity of  limited extent 
still persists.
     On the banks of Juniper Creek there is nothing of  a thermal character 
except a few quiet pools embedded in ancient sinter, and  along a little 
tributary of the creek from the south, a small number of acid  springs, 
characterized by meager sulphur deposits, yield not more than 0.1 sec.  ft. of 
warm water. --end--
 
OK, so two Google Earth photos are attached. The first serves as a map to  
the area, with the trailhead, Morning Mist/Culex, and a really odd looking  
feature marked. The second photo is a close up of that strange feature, 
which my  wife calls "The Alien."
 
What is it? Any explorers out there game of a 15 mile (round trip) hike?  
(Won't be me!)
