Bus service to the Maroon Bells Scenic Area will gear up June 9 for its 40th season, according to the U.S. Forest Service. “That’s 40 years of reducing traffic congestion, carbon emissions and other impacts in the environment by limiting car trips,” the agency said in a statement. More than 300,000 people visited the area last year for day visits, camping or venturing into the Maroon Bells-Snowmass Wilderness. The bus service provided by the Roaring Fork Transportation Authority will operate from June 9 through Oct.
