Belmont Gardens offered more than just a less congested setting for its new residents. Due to its proximity to rail along the Chicago, Milwaukee, St. Paul and Pacific Railroad, the area developed a plethora of industry that still survives in the city's Pulaski Industrial Corridor. It was adjacent to his own factory that Mr. Walter E. Olson built what the Chicago Tribune put at the top of its list of the "Seven Lost Wonders of Chicago", the Olson Park and Waterfall Complex, a 22-acre garden and waterfall remembered by Chicagoans citywide as the place they fondly reminisce heading out to for family trips on the weekend. The ambitious project took 200 workers more than six months to fashion it out of 800 tons of stone and 800 yards of soil.
