8k is pretty high when you’re spiking straight up from sea level. Breckenridge is pretty much surrounded by 12k.
It’s tough to hit 90° at 1.5k out here, but then you get east of the Black Hills and Pierre occasionally hits 120°.
Pretty much peak blueness potential right now…solstice at solar noon. The less atmosphere for the light to travel through the less blue that is scattered away.
Up to 80.4°
