The Blair Witch Project
With 63,000 acres of forests, lakes and hiking trails, Seneca Creek
State Park in Montgomery County, Md., is a nature lover's paradise in
reality and a creepy place of doom in the psychological thriller The Blair Witch Project,
which follows three students producing a documentary about a local
witch. Black Rock Mill (pictured) is the starting point for the trail to
Coffin Rock, where the three students camp for the night and where five
men were supposedly ritualistically murdered.
