Treasure Mountain Junior High School served eighth and ninth graders in Park City, a mountain resort town where the economy is built around skiing, tourism, and outdoor recreation. The school’s academic performance placed its overall proficiency across tested subjects and grades in the top quartile relative to other districts in Summit County. On state assessments, roughly three out of five students scored proficient or above in math and in English language arts, while about three out of four students reached that benchmark in science.
The student body of this junior high school was predominantly white, and roughly one in five students came from households qualifying for free or reduced-price lunch. The school did not report counts of students with disabilities or English learners, so a parent may want to ask the district for those numbers directly. The campus enrolled a modest number of students for its grade band, drawing from a community where housing costs are extremely high. A typical home in the school’s zip code was valued well above the state median, and rents were steep, which means the families who live in the attendance area are largely those who can afford one of the most expensive housing markets in Utah.
The school itself no longer exists. Treasure Mountain Junior High School closed at the end of the 2024-2025 school year and was demolished in 2025. The closure came with a district-wide grade reconfiguration. Eighth graders now attend Ecker Hill Middle School, which serves grades six through eight. Ninth graders now attend Park City High School, which serves grades nine through twelve. This permanently changed the secondary school feeder pattern families had known.
The demolition process drew attention for environmental compliance issues. In 2023, the district was found to have broken an agreement with the Environmental Protection Agency after moving soil contaminated with lead and arsenic behind the school; the district later removed the contaminated material during the following school year. In 2025, an anonymous tip led to a Utah Department of Environmental Quality investigation into improper discharge of contaminated water into a nearby creek during demolition, and the district also received a compliance notice related to asbestos handling at the site. These incidents affected school facilities and required remediation while the school was still in operation or during the demolition.
Park City itself is a place shaped by tourism. The permanent population is modest, but the number of annual visitors is many times that. The historic Main Street functions as a walkable core with shops, restaurants, galleries, and festival space, including events tied to the Sundance Film Festival, which relocated to Boulder, Colorado after 2026, though the Sundance Institute’s Utah office remains in town. The city operates a free intra-city transit system. Two major ski resorts, Deer Valley and Park City Mountain, anchor the local economy along with outdoor-product companies that maintain headquarters in the area. The city is preparing to co-host the 2034 Winter Olympics, reusing much of the existing infrastructure from the 2002 Games.
For a family considering this district after the closure, the key shift is that there is no longer a separate junior high campus for eighth and ninth graders. The academic pathway now moves students from a middle school directly into a comprehensive high school a year earlier than before. The district’s overall test results in Summit County were strong, and the housing market remains a barrier for many. A parent will want to understand how the district handled the environmental cleanup and how the new configuration is working in practice. The school’s history is now just that.
