This is a small detail from one of many frozen waterfalls at Ricketts Glen State Park in Pennsylvania. This park features more than 20 waterfalls that freeze during cold spells. The hiking trails that take you past the waterfalls are a delight in winter, as long as you have the required gear including crampons and ice axe. This small detail encapsulates the transition from flowing water to ice and back again each winter. Processing in black and white helped bring out the many facets of the ice.
