Description

A set of steps, or rungs, inserted in two uprights to serve as a means of ascending a cliff-face

Topo50 description

ladder_pnt is used where the featutre is too small to hold at 1:50,000 as a line feature. Ladders were originally captured by surveyors in the field. As they are not always visible on imagery, these features are left unchanged unless more current information becomes available
