Bring lunch, water, snacks, sunscreen, insect repellent if you need it, and a scope if you have one.
The DFO Field Trip for Sunday, September 8 will be to Chavez Trail and Beaver Brook Braille Trail led by Paul Slingsby (303-442-3728). This will be a half-day trip. Meet at the lower end of the Stegosaurus Park-n-Ride at 0645. We will carpool from there, leaving at 0700 sharp.

This will be a slow walk of about 3 miles on smooth but steep Denver Mountain Parks trails with some short unmaintained paths. Will visit an aspen forest and some ponderosa/Douglas fir forest with a small spring-fed creek. Many mountain species will still be present and some may have gathered in numbers. Aspen may have begun to change into their fall colors.
