Matthew Henson was the first African American Arctic Explorer, which kind of makes him like a geocacher in the winter climates here. The park named after him is a greenway along the Turkey Branch of Rock Creek. The park runs from Aspen Hill to Layhill, Maryland, linking the Rock Creek Trail with the Sligo Creek Trail.
Cache is a small container hidden from plain sight. It is directly next to a parking lot, so it may be a cache and dash for some, but for others it may take a while to get the cache in hand. Once you are done, take the time to read up on your Matthew Henson history!
