Abstract
A boulder rolling down a slope is caught with an energy absorbing device to dissipate a portion of its kinetic energy and to redirect the boulder downwardly into the ground to absorb the rest of the kinetic energy and to stop it. This is accomplished by temporary deformation of joints in the energy absorbing device to dissipate the kinetic energy and redirect the boulder downwardly into the ground. The energy absorbing device will return substantially to its undeformed state for intercepting additional boulders which may roll down the slope.
