There are many names for this trail, but it's the trail on the West side of the Maston group of trails. Maston is known for its wonderful winter running; in the heat of the summer, watch out!
This one has rolling and relatively flat terrain that is just fun. There are a few rocky sections, but easy to get around. You can also enjoy great views of the Cascade Range out to the west.
There are no trail markers yet, though the trail is well established, and the new parking area on the South side is impossible to miss - it's huge. There's a restroom and several picnic tables at the trailhead.
The Juniper Trailhead to the north is an optional starting/ending point for this run.
