I must confess that it is difficult to portray this physical phenomenon in a two dimensional picture, put fissures are large crevices (or cracks) in rocks. They can be very dangerous as they often intersect areas close to trails and form a hazard for hikers.
Naturally hikers need to be vigilant at all times, but when hiking with children, one needs to be doubly aware. Can you see the large crevice with the two small boulders that have fallen in the crack? That could be a person wedged in there. To make matters worse, some areas near the edge of the fissures have small shrubs along the perimieter which might camouflage them a bit.
Of course there are warning signs alerting hikers of the dangerous fissures and to alert families to hold children close.
NOTE – If you haven’t discerned the fissure, look at the picture below. The arrows point to the walls of the fissure and the red-orange ovals show the boulders that are wedged in the crack.
