Now that the whole trail has been explored it's possible to leave a car on the Oasis end of the trail, park at Murphy creek, and have an enjoyable walk through a mostly Pine and Birch forest. From the Murphy Creek end, the trail makes a fairly gentle climb, from level ground to level ground. At least 7 distinct changes in elevation. It's a long walk walk (or mountain bilke/motor bike ride), but there are 5 caches along the trail, and a big sandy hill at the end that is fun to run and bounce down.
The trail leads right to the old road so there is no need to stray off the trail. It looks like the road was built so some equipment could be moved to the base of the gas line right-of-way down by Murphy Creek. The cache is hidden near the top of the road.
The other caches along the trail are:
