Malcolm W. Martin Memorial Park

I was there yesterday:

Malcolm W. Martin Memorial Park, located on the East St. Louis Riverfront, complements the renowned Jefferson National Expansion Memorial, home of the St. Louis Gateway Arch, across the Mississippi River. Eero Saarinen, designer of the St. Louis Arch, originally included a park on both sides of the Mississippi River; decades later his vision has become a reality.
Malcolm W. Martin Memorial Park boasts two distinct features: the Mississippi River Overlook and a fountain known as the Gateway Geyser. The Gateway Geyser erupts four times a day during the spring and summer months. The main fountain of the geyser was designed with the capability to reach 630 feet, as tall as the Arch itself.
The geyser is surrounded by a small lake and four fountains, representing the four rivers that meet at St. Louis. The geyser is powered by three 800 horsepower pumps, and can shoot 7,500 gallons of water per minute at the rate of 250 feet per second. The four smaller fountains are powered by a 125 horsepower pump. The lake surrounding the geyser is six acres, 600 feet in diameter, and contains more than a million gallons of water. Nearby aircraft are alerted by a beacon on the roof of the pump house when the geyser will soon go off.
The Mississippi River Overlook stands 40 ft. tall on the opposite end of the park. Its tiered structure boasts stainless steel railings and architectural concrete. The MRO offers visitors marvelous views of the park, both sides of the Mississippi River, and the St. Louis City Skyline. The new park also provides passive open green space for visitors to enjoy. The Metro East Park and Recreation District owns and operates the park grounds. The park is the result of a partnership between MEPRD and the Gateway Center of Metropolitan St. Louis.

I went up the Mississippi River Overlook, but I missed the Gateway Geyser.  I may have to check that out sometime, that sounds badass.  It was a very nice park, and the folks there were very friendly.  It gives a very nice view of the arch, and allowed me to fit the company product trailer I was driving into a picture featuring the arch.
