Field Exploration

Waterfalls – they seem to have an almost magnetic ability to draw the interest of the outdoor enthusiast and generate a sense of wonderment on the part of every observer. But why are waterfalls seemingly so rare and how exactly do they form? Roughlock Falls provides us with the ideal opportunity to investigate the geologic forces behind their formation as well as a chance to hear the roar and feel the mist of the plunging Little Spearfish waters as they impose their will upon the rocks below. Join us with camera in hand for this exciting lesson into the science that makes it all possible.
