Treetop Noctilucent Clouds
Noctilucent (night shining) clouds are a rare and beautiful type of cloud. About 50 miles high in the mesosphere, no other cloud is higher. They are only seen in the summer, usually from high latitudes between 50°-65°. Occasionally they are sighted from lower latitudes. After trying and failing many times to spot them from Wyoming, the morning of July 10th brought this incredible display.
