Teegate, I always enjoy your photos and videos but I especially appreciate your video post titled "Stream Depth". It absolutely terrified me that yet another pine barrens water feature could be so unassuming yet so dangerous. From this web site, I also learned about the sand ledges in some quarries and blue holes that can collapse under the weight of an unsuspecting wanderer. This makes me appreciate when my wife warns me not to explore the beauty of our Garden State treasure alone as I frequently do.
