I'd pick late July/early August for the statistically best chances of a good time. Summer up there is short (that's part of why the plants are so delicate). Melt-out at Paradise is usually early to mid July, and autumn weather starts around Labor day, sometimes sooner.

Try to stick to trails and rocky surfaces. If you're committed to meadow-stomping, find a spot that's already worn bare from others rather than trampling healthy plants.

Scintillation causes blurring of images over distance. The mechanism is that rising bubbles of warmer air act like lenses. This kind of lensing is what causes stars to twinkle, and also the "heat shimmer" you might see above a hot roof or hot pavement.

Scintillation is generally weakest in the morning when the ground is cold.
