ABSTRACT:
A preferred tower of a lookout is triangular in cross section and tapers inwardly from the bottom to top. The tower has an upper and a lower section of about equal lengths, and the tower can be easily and quickly disassembled, and then the sections nested for easy transportation and storage. When the sections are nested, wheels that extended outward from a side near the bottom of the tower become wheels of a dolly to help transport the components of the tower and any load tied upon the nested sections. An extending platform as a stand or a footrest is removable from near the top of the tower and readily stowed within the nested sections.
