If you hike at over 30 degrees Celsius and are completely sweaty, you will be surprised by the approximately 8 degree cold air flow at this point. The phenomenon is caused by a heap of scree where warm air penetrates at the top, is then cooled by the large, cold blocks of rock and thus exits at almost "mountain temperature" due to the difference in density at the lower end of the heap.
