Produce a detailed written description of a foreboding scene outside a cliff with ridges and foundation beams.
assistant
Square foundation beams, laid an arm's length apart, have been staked sideways across the path and partially buried beneath crushed rock. These planks, stretching from the top of the steep slope to the switchback turn below, create a series of bumpy ridges that catch at passing caravan wheels, preventing them from speeding through the flimsy netting and flying off the edge of the cliff path.
