The fridge isn’t working at this higher altitude (7500’), and I suspected that it’s a bad regulator, so I went into town to buy a new one. Old regulator removed:
New regulator installed:
Turns out the problem didn’t go away. RV propane fridges aren’t rated to operated above 5500’. I did a little reading, and it sounds like at higher altitudes the ratio of air to propane becomes biased towards propane because there’s less air at altitude. The solution seems to be to reduce the propane regulator’s pressure to bring the ratio back into balance. I tried this and the fridge seems to be working now. I’ll have to buy a manometer to be able to accurately control the propane-air ratio.
While in town I visited the San Luis Valley Museum:
The museum’s collection is eclectic but interesting:
On the way back to where I’m camping, I stopped at the Blanca Wetlands, but it turns out they’re closed for seasonal bird breeding:
Back at home. Not bad!
In the afternoon, the neighbors came out for a visit:
The last stop was the reason most people come to Salt Plains NWR: to dig for Selenite crystals. The “road” out onto the salt flats was very rutted, so I parked here and decided to run the rest of the way:
I found an existing hole and continued working it:
I found dozens of Selenite crystals:
I overnighted at a gas station in Alva, Oklahoma. See the trip map for today’s drive.
The site preserves the childhood home of George Washington Carver, agricultural scientist who lectured at Tuskegee Institute, which I visited on our Winter 2019 trip. Carver was an infant slave when he and his mother were kidnapped by slave raiders. A bounty hunter was hired to recover them, but he only brought back an infant. The child raised as George Washington Carver could very well be a different person than the infant slave kidnapped from the Carver homestead.
I toured the visitor center:
A replica of Carver’s lab at Tuskegee Institute:
I ran the park’s nature trail:
A replica of the home in which the Carvers raised their slave George:
Graves of George’s owners:
I continued into Kansas to overnight at Cowley State Fishing Lake. See the trip map for today’s drive.
