Event Details

  • EIDA = Equity Inclusion Diversity Accesability
  • Join Denver Zoo and Denver Audubon on a Boreal Toad Community Science project to inspire, connect, and engage minority communities in the outdoors. People of color are encouraged to come and participate in surveying the endangered Boreal Toad population of Colorado at Hassell Lake. Denver Zoo will provide training and transportation on site. Details and additional information on Boreal Toads are provided below. We can't wait to see you there!
  • Hassell Lake – Sunday August 14th

  • Estimated Total Hiking Distance – 3.2 miles
  • Elevation Gain – 750 ft 
  • Maximum Elevation – 11,400 ft
  • Difficulty – Easy-Moderate
  • Off-Trail Hiking – Fairly open, not much bushwhacking
  • Nearest Town – Idaho Springs
  • Driving Time from Golden – 1 hour 
  • With just over 3 miles of hiking this will be a fun day at a wetland right outside of Denver. After about 1.5 miles of hiking we'll reach our target wetland. We'll survey the ponds and slow streams along the edges of Hassell Lake. Here you'll learn our data collection protocols and how to look for boreal toads. After spending several hours at the wetland (surveying and enjoying lunch), we'll hike back to the trailhead to wrap up the day.
