Within a few years, nature reclaimed the park grounds. Collins sold off much of his remaining to the state as a nature preserve but he held on to the where the park and picnic grove were, hoping for a buyer. In 2005, the city entertained an idea to create a senior citizen housing complex there. But in 2006, local entrepreneur Eric Suher purchased the of property from Collins for $1.6 million. By the end of that year, the parking lots and midway were cleaned up of all debris, and a new sign was placed on a new gate at the park entrance: "See you in the summer of '07 -- Mountain Park." However the sign disappeared in the spring of 2007 and the property sat idle throughout that summer. Suher then purchased the nearby Castle Hill Apartment complex. Few reminders of the park remained: the entrance to the Mountain Flyer, the decaying mini-golf course, the large blue picnic pavilion and one of the original stone water fountains. By December 2008, the entire park property had been graded and much of the picnic grove had been cleared. The picnic pavilion that Araserv constructed in 1971 remained as the lone reminder that the property once was home to a popular attraction.
