The Civilian Conservation Corps (CCC) constructed several buildings in the park, including a lodge, a bunkhouse, six cabins, a manager’s residence, and a barn. CCC workers also enhanced the site’s rolling terrain to include Lake Toppaska to the north and Lake Palila to the south, with winding access roads between them. The entrance retains four coursed stone piers and two steel stanchions that once supported a spanning entrance arch. Reached by wide stone stairs, the lodge occupies a prominent hilltop site and is impressive for its randomly coursed stone walls, chimneys, and fireboxes, for its heavy-timber columns and beams, and for its two front-facing gables of irregular weatherboards, a combination of materials representative of the CCC’s rustic style.
