Holt Arena is an indoor multi-purpose athletic stadium in the western United States, located on the campus of Idaho State University (ISU) in Pocatello, Idaho. It is the home field of the Idaho State Bengals of the Big Sky Conference and sits at an elevation of above sea level. History Originally named the ASISU Minidome—named after the Associated Students of Idaho State University, who funded construction—it opened in 1970 at the north end of the ISU campus. The indoor facility replaced the outdoor "Spud Bowl" as the Bengals' home football stadium. The venue was renamed in 1988 to honor Milton W. "Dubby" Holt (1914–2007), ISU's athletic director from 1967 to 1989. As assistant athletic director, Holt conceived the indoor arena in 1966 and it was designed by architect Cedric M. Allen. Although a controversial design proposal for the time, ISU students voted to appropriate not more than $2.8 million to the project two years later. The arena was built entirely with these voluntary student funds. With over 56% in favor, ISU students approved a $12 increase in semester fees to fund the stadium in early 1968. Holt Arena is the oldest enclosed stadium on a college campus in the United States and the second-oldest overall. Only the Astrodome in Houston, completed in 1965, predates it. Since the Astrodome's 2006 closure, Holt Arena has been the oldest enclosed stadium in use. The original artificial turf installed in 1970 was Poly-Turf. After 41 football seasons on Poly-Turf and AstroTurf, infilled synthetic turf was installed in Holt Arena in July 2011. Similar to FieldTurf, the SoftTop Removable Matrix System is also installed in AT&T Stadium in the NFL. Holt Arena is undergoing major renovations which are planned to be complete by the 2023 season. A new turf is being designed as part of the renovations, and the new turf is projected to be installed by the 2022 season. Additional uses Holt Arena also serves as home for the ISU indoor track and field team and men's basketball team. It also hosts high school football games, the famous Simplot Games high school indoor track meet, along with other sporting events, rodeos, concerts, and other activities. During ISU's run in basketball to the Elite Eight in 1977, they won the Big Sky regular season title, which allowed them to host the four-team conference tournament, which they also won. The Bengals were allowed to stay home
