Hilltop was as the name implies, on top of a little hill, looking out over the mountains from the flat valley, this tub had a little valve on the side so you could adjust the temperature of the water, very nice indeed! We stayed here for 5 days while we were touring in the Mammoth Lakes, and Bishop region. One night we went across the way from Hilltop and found Wild Billy's springs, this was a very large pool, and although we had it to ourselves for awhile a group of 15 people (ski and race coaches from the local mountain) ended up joining us, so we didn't stay very long.
The last springs, and the most geologically beautiful and mystifying, was Travertine. Here there were large (10 foot plus) fins of rock and at the top of them the hot water bubbled out, the water then ran along to top of the fin to the downhill end, where it fell into the pools. This was indeed my (Hannah's) favorite springs.
