According the legend, the pool is said to have limitless depth however, this is not true. The pear shaped pool is about 30 feet deep and 30 feet wide when it is full.
This pool was formed over time as water followed zones of weak rock. The water would cut down through the rocks to form this gorge. The force of the water flowing over the rocks beneath the falls formed the larger depression. Large outcrops of mica schist and quartzite (Wissahickon Formation from the Lower Paleozoic age) surrounds the pool.
The rock around the pool have had to deal with extreme weathering which has decomposed the mica schist leaving mostly quartzite. This is visually apparent when you compare the a shiny piece of schist from the trail to this weathered version near the water.
The above coordinates will take you to a a rocky area at the base of Devil's Pool. From here, you can see just how eroded the area is. If you peer into the water, you will notice that the bottom has an almost sandy texture with very few rocks. This is a combination of eroded pieces of rock settling on the bottom and not getting washed away.
