@skua It is a state park and really remote. Everything well secured and rangers live there year round.

It had a small population up to WWII. A few hundred vs the orginal thousands. Mining stopped due to the war and the last people left. The family that owned the mine bought most of the town and initially had caretakers. Gave it to the state in the 1960's once it was clear there would be no more mining.

@MartyFouts They have been replacing roofs and making sure things stay secure. Keeping critters out. But not much more.

I saw some pictures from the 1970's when places still had paint. You can see remnants on some buildings, in protected spots.

@Der_Michi Tioga Pass was built in the 1960's. Even by California standards, it is modern. Yosemite Park attracts people from all over the world, including those who have never driven on a mountain let alone a pass so the park tends to be heavy handed in how they communicate. You should see how they handle snow!

That said, I've gone over multiple Sierra passes and Tioga isn't the worst. The back side of the Sierras have a 25% grade, vs the front side's 2%. Crazy lopsided.
