(left) Memorial Building, on the west bank of the Portneuf River at Fremont Street. The Memorial Building was built in recognition of World War I veterans and dedicated on May 30, 1926. Alex Mathers, Pocatello contractor, was the largest individual contributor to the building cost. Note the piled up rip-rap on the west bank of the river, consisting of boulders of basalt, carried by the Lake Bonneville Flood. The Memorial Building is one of the few Pocatello public meeting halls where alcohol can be served. The open-air porch on the second floor has been closed in and the concrete Portneuf River flood control channel has replaced the wall of boulders.
The long-term plan for the Portneuf Greenway includes a riverside plaza around the Memorial Building.
One block downstream, at the north end of what is now Memorial Park, is the site of the power plant and dam of the Pocatello Power and Irrigation Company, which provided electric power to Pocatello until 1902. Boaden Photo, Bannock County Historical Society Collection.
