After climbing back down we hiked the rest of the way to the falls in the mid 90 degree heat. By the time we arrived we were both quite hot and I decided to jump into the pool without taking time to cool down first. The water is at least 68 degrees if not colder (I didn't wait to see how far past that my watch would go) and was a bit if a shock to the system.
Unfortunately the quick change in temperature was the catalyst for a nice headache making me dread the hike back. However, a storm had begun to roll in and the temperature dropped ten degrees to about 84. It's amazing how much of a difference the temperature can make on efficiency. We hauled ass back to the car at almost a jog to beat the storm, a pace that I could have kept up all day in those conditions and felt fantastic. It started raining and briefly hailing about a mile from the parking lot but we made it back to the van albeit soaking wet.
