Calder Park soon developed into one of the finest amusement parks between the Missouri River and the Golden Gate. The soggy swampland created by a spring was cleared to form a small lake for boats and amusement. Other attractions developed over time and included a merry-go-round, bridges, a large dance pavilion, a bandstand with a suspended acoustical shell, a racetrack for horses and later motorcycles, bowling lanes, a roller-skating rink, a log flume-type waterslide, and traditional playground equipment. The park passed through different ownerships including the Rapid Transit Street Car Company which ran the park from 1891 to 1902 and extended streetcar service to the park along 700 East and installed electric power throughout the park. At its peak, the park was attracting over 100,000 patrons per season. The LDS Church Granite Stake assumed ownership and changed the name to Wandamere Park. "Wanda" was claimed to be of Indian origin, meaning "beautiful place," while "mere" is Anglo-Saxon and signifies "little lake" or "clear pond." By 1921 interest in the park was diminishing and it was sold to Charles Nibley, who donated the land to Salt Lake City on the condition that it would always remain open park space. That condition was met by transforming the park into a nine-hole golf course which Salt Lake City still operates.
