Afton, Thayne, Periodic Spring and Grays River Road to Pinedale


Afton / Thayne

The Afton and Thayne (Star Valley) area was on our list of possible relocation
towns so we were here to check it out.




Downtown Afton and the Elk antler arch


Periodic Spring

The spring that breathes

We parked and walked the mile or so up to the valley that the spring lies in.
The spring lies in a small canyon of to the left of the main valley
The perodic spring is a cold water geyser.  The flow cycles on and off from
late summer through winter.  The water gushes out of a sheer ledge and cascades down
a hillside to swift creek. Suddenly, the flow stops.  After 12 to 18 minutes, the
water gurgles to the surface and the cycle repeats.



The opening that the water comes out.  Very man made.
It was stainless steel and supplies Afton with a good bit of its water.
It goes from no flow to full in a minute or so


Grays River Road

We started south of Afton on Smiths Fork Road and went up over
Commissary Ridge El. 9,250 Ft.
Tri Divide Basin with drainage to the Great Basin, Columbia River and the Colorado River
Bull Moose along Grays River road
Shot Hole Spring
Along the Grays River
Another moose along the road


We then went up over the Wyoming Range and headed towards Daniel on Cottonwood Road.
Up over the pass it was snowing.  We we got to the mesa it begining to clear.  We saw
a number of grouse and pronghorn along the Mesa
