Welcome to the 2025 Taconic Region NYS Park Summer Geocaching Challenge. Please see OL 1 for more information. This is a bonus cache. It does not contain a stamp for the passport; it is simply for your enjoyment.
“Our Banner in the Sky” (1861) depicts the American flag as a transient arrangement of sky, clouds, and stars. It is currently privately owned. https://commons.m.wikimedia.org/wiki/ File:Our_Banner_in_the_Sky_by_Frederic_Edwin_Church.jpg
