Mary Riddle, Chief of Planning and Environmental Compliance at Glacier Park: "What We Know and What We Don't Know for 2020: Planning, Construction and Other Program Activities in Glacier National Park" will be our third and final presentation for the year. And how fortunate to have Mary Riddle, Chief of Planning and Environmental Compliance, with 25 years of Glacier National Park experience as our presenter. Topics to be covered include the ongoing visitor monitoring program, trail use, parking lot congestion, resource impacts of 2019 and the Many Glacier Road rehabilitation. Mary's question and answer period will most certainly be a lively one. Questions call Teri at 406-261-1840
