Take the steep trail South of the fence. Be on the lookout for any poison oak. The black non-round bottle is at the base of a large tree. Please replace the cache just as or better than how you found it. Now that you are about halfway to the top, why not keep going. There is a great view on the west side just passed the Letter cache. Congrats to trailtrekn for the FTF. Enjoy the hike and the view on the other side.
Note: BYOP, carefully open the container/baggie, sign the log, completely seal baggie with log inside, tightly close container and replace cache out of plain view to same location in description/hint.
