Then I see that it duplicates the outline of Magdalena Peak on the southern horizon.
And I think of a pleasant piece of psychedelic pop from years ago.

|Steppe bison were the ones painted at|
Altamira Cave in Spain (Wikipedia).
"The scientists compared the mitochondrial DNA from the fossil found at Ch’ijee’s Bluff [Yukon] to that taken from 45 other bison remains, including one of the oldest and most interesting specimens, the fossil of a giant, long-horned bison — belonging to the species Bison latifrons — found in Snowmass, Colorado.• All the kool kidz will be using these on their desert campouts soon. The Burners will have to have them.
“Bison latifrons is an interesting beast,” said Dr. Duane Froese, a geologist with the University of Alberta, in a separate statement.
“Its horns measured more than two meters across at the tips, and it was perhaps 25 percent larger than modern bison.”

But if you get a lifetime pass before the change is implemented, it will cost only $10. Passes can be purchased online for an additional service fee of $10 or at any of the parks without an extra charge.It's one good deal. Just show that pass to the ranger at the gate, and a whole carload of people get in. Some groups have been known to rearrange themselves so that the pass holder is driving, but I don't know if that is really necessary.
National Park Service officials are unsure how long it will take to implement the change, but it’s expected before the end of 2017. Meantime, they are spreading the word informally.

Many visitors wonder: Why is there so much sand only here, but not at other locations along the mountains?That is the San Luis Valley on the lower left and the Wet Mountain Valley to the upper right, so the top of the photo is roughly northeast.
In this view from space, part of the answer becomes clear. The Sangre de Cristo Mountains are curved here, and at the same location are low passes to funnel wind and sand from the valley floor into this pocket.
Then why doesn't sand accumulate, for instance, at the base of La Veta Pass to the south? The mountains also curve there below a low pass.. The answer is that this northeast part of the San Luis Valley is a closed basin. Streams carrying sand into this basin don't exit, so all the sand they carry is deposited here. In the past, these streams fed into huge lakes; when these lakes disappeared through natural climate change, vast quantities of sand blew and accumulated here below Mosca, Medano, and Music Passes. In other parts of the valley, and in most places in the Rocky Mountains, sands are continually washed away and carried downstream into larger and larger rivers.
