portagerunner: " Link to trip report. I was up there last month and did some snow snowshoeing out of EP 77 South Hegman Lake on the echo trail to the pictographs on north hegman. Out and back from the parking lot is about four miles. You could connect to the angleworm trail if you wanted to go further."
Thanks. Jodi Middendorf had a video of this trip on her YouTube channel recently, so it was on my list of possibilities. Looks like a neat outing.
