Every year on the third Friday in May, thousands of people around the world participate in Endangered Species Day by celebrating, learning about, and taking action to protect threatened and endangered species. Wildlife refuges, zoos, aquariums, gardens, schools, libraries, museums, community groups, nonprofits, and individuals hold special programs or events for people of all ages.

This year in honor of Endangered Species Day, we will be offering a series of interpretive programming opportunities for visitors to attend at Radnor Lake. This interpretive programming opportunities will be two fold:

1. Endangered Species Day: White-water Crowfoot thru a State Park Ranger’s Spotting Scope programming offered at 8am-9am, 9am-10am,
