Trail Overview
Named for the Merten family who owned orchards in this region during the late 19th and early 20th century, the majority of Mertens Avenue is a rough but generally well-maintained gravel road. The road surface is primarily rough rock in almost a cobblestone orientation, which can give a washboard-like feel at times. The track has an elevation change of over 600 feet, which is mostly gradual from end to end with a few tight turns and short sections with steeper grades. There are several areas prone to minor ruts and washouts. Passing carefully is possible at all but a few points along the route. Towards the north end of the track is Outdoor Club Road, the only spur trail off of Mertens Avenue.
History
The Merten family owned a large portion of this land in the early 1900s and built an extensive apple orchard here in the early 1900’s. During the Great Depression, they chose to turn the land over to the state of Maryland.
