RIVER CROSSING IS DANGEROUS. CROSS AT OWN RISK - Especially during the Spring and Summer, the water level can be high and the current is strong. If you choose to cross in high water, use the upper crossing. However, even at this crossing, the water will go up to the torso of an average-sized human.
