Abstract: An extension ladder and tree stand for supporting a seated or standing person on an elevated platform against a tree trunk for hunting, photography, and the like. The ladder and platform collapse into a compact size and shape for carrying by a person. The ladder is in telescoping sections. Alternate steps of the ladder slide to the middle of each telescoping section. This provides twice as many steps as sections, reducing the number of telescoping sections by half. This minimizes weight, size, complexity, and expense. When deployed, all parts remain safely assembled in all positions. Captive spring loaded pins fix the telescoping sections in extended or retracted positions, and fix the sliding steps in a middle position of each section. A folding seat on the platform has a cushion that reconfigures into a back cushion for carrying the collapsed assembly on the back of a person.
