Texas' seventh highest summit is found in Guadalupe Mountains National Park. In fact, this remote piece of public land is home to eight of the ten highest peaks in the Lone Star State! An ancient fossilized coral reef, the Guadalupes were uplifted revealing large deposits of gypsum, limestone, calcite and obviously fossils. The porous stone allows water to percolate easily into the bedrock, creating an immense cave system beneath the range; several miles to the north, Carlsbad Caverns National Park showcases this same geology.
Hikes in the Guadalupe range entail very dry and often windy conditions. A gallon of water per person per day is a good rule of thumb, but on a hot summer or fall day, even this may not be enough. Based on the higher elevations, these mountains provide habitat for black bear, mountain lion and many trees, such as Ponderosa Pine, that are usually found hundreds of miles to the north. This "sky island" is a remnant of times when Texas maintained a much cooler climate.
