It got a bit above 100 here yesterday, even though I'm up against the foot of the mountains living at 6000 feet, with 14,000 foot tall peaks less than five miles away to the West. But it was undoubtedly a few degrees warmer down 2000 feet lower in the valley below us just a couple of miles to the East. Not at all surprising for us here in the High Desert in July, less than 30 miles out of Death Valley!

Does your boilers produce steam faster than ours? I know water will boiler faster at 6000 feet in elevation, but at a lower temperature.  Also you lose maybe 1-2 psi in vacuum than you have at sea level!
