We hiked the Historic Railroad Trail yesterday, 6.5 miles round trip, from Boulder City NV to Hoover Dam along Lake Mead. It’s a trail now, however was a railroad when they built Hoover Dam in 1931. It was only 90 F (32 C), not hot by Vegas standards.
Next weekend will be 108, so caution is definitely advised, if they haven’t closed the trail. Heat here absolutely can kill.
It was seriously windy, with sustained gusts of 50-60 mph, which made walking difficult at times. Deserts can be like that.
One sign shows where Ragtown was. The poorest of the workers lived there. No running water, no electricity. Baking heat.
