## About

A winter evening of astronomy at Observatory Park at Turner Farm in Great Falls, for ages 3 to adult. Staff lead guided star-gazing and let visitors look through the park's telescopes, and around the campfire storytellers share ancient tales about the constellations. Other games and activities run through the evening, and hot chocolate is included in the registration fee. Dress very warmly — the program is outdoors after dark — and note it is cancelled in rain or snow.
