I was in the area to place some other caches when I saw this artwork.
From the MNC-PPC website: "Through the Art on the Trails program, local artists repurpose materials found along nature trails to create sculptures, totem poles, and other park fixtures that reflect the wildlife and environment of the trail. In the summer of 2015, students and local artists created eight beautiful works of art along our trails to share with the community. "
As this cache is on MNC-PPC property, please abide by all park rules, like the park is closed from sunset to sunrise.
