Traps are subtle and include primarily sandstone pinchouts or gradations into impermeable facies. The play covers approximately 8,300 sq mi. Reservoirs: The Leo consists of sandstone, carbonate, shale and evaporite, which were deposited in aThis hike follows the Dakota Sandstone wall (the trail name is a misnomer as the wall is not a igneous rock dike). There are two trailheads, a north and a south, and the trail can be hiked in either direction. This trail begins at the north trailhead and makes and out-and-back trip. If you're looking for a longer hike, you could continue onward from the turnaround point.
