In 1972 billy barr (he spells it lowercase) was a Rutgers University environmental science student and did some research in Gothic, Colorado, a ghost town built around a silver mine. The native New Jerseyan returned after graduation and has lived in the town as its sole full-time resident ever since. He has also taken meticulous snowfall and temperature measurements, which have proven valuable to climate scientists.
From Oddity Central:
"The trend I see is that we're getting permanent snow pack later, and we get to bare ground sooner," barr says. "We'll have years where there was a lot of snow on the ground, and then we lose snow sooner than years that had a lot less snow just because it's a lot warmer now."
