While enjoying the scenic views throughout this entire area, you will find many interesting plant species. The desert willow is a small tree or large shrub native to Mexico, south-central Texas, and Southern California. It technically is not a "willow" as its name suggests as it is part of the bignonia family. This tree/shrub is drought tolerant, fast growing, and easy to maintain. These bloom most heavily in May and June, but will continue blooming sporadically throughout the warn season after rains.
There is a small, nice, paved pull off area here, but you will be off the pavement to retrieve this cache. I always want to caution people that are not familiar with our part of the world here. You are in the desert of west Texas. Nearly everything here wants to "stick you, sting you, or bite you". We have numerous venomous snakes in the area including rattlesnakes and copperheads. While this plant does not have thorns, many in the area do, be careful.
The cache itself will be a small bison hanging in the shrub/tree. It only includes a log, so bring your own pen.
