I’ve forgotten the exact year, but I witnessed one of the long-ago Nevada atomic explosions. It was on a Saturday morning. I was with my brother, in the California Sierras on a two day weekend fishing expedition above Bishop. It was around 5:30 AM and we were near the top of Piute Pass (14409 ft), above the timber line, sitting on rocks and looking down our trail into the very-dark Southeast direction ... The sky suddenly flashed -— followed minutes later with sounds of the explosion booming around inside that high-mountain area.
Awesome recollection - thanks for posting it!
