Geocache Description:

This virtual cache is at the old glass factory in Valley Park.

I made this a virtual cache since this area is prone to flooding in the Spring.

***************** Update on the old factory 11/26/01 *****************

miken927 has scanned the text that goes with the picture he included with his log. It is included (MSWord Doc) with the other images on this cache.

I finally found out some information on the glass factory from the Valley Park Library. The company was "St. Louis Plate Glass Company" and was established in 1902. Even by today's standards the plant was HUGE. (see pictures). Managers and skilled workers were brought from England, Switzerland, and Germany and workers were "pirated" from PPG plants in PA, IN, and Crystal city, MO. There were so many migrant workers from Poland, Czechoslovakia, and Italy that they lived in tents along Marshall Road. The company also owned a sand company in Pacific which they needed to make the glass. They had two railroad spurs which I assume brought in the sand and coal, and took out the finished glass. There were two, 12 hour shifts, 7 days a week and the men were paid $3.00 a day. 12 men carried the finished glass with straps. If the glass broke, a small cut required 150 stitches.

In 1915, the factory was destroyed by a 100 year flood. It was rebuilt but a boiler explosion in 1916 burned the place down. East coast investors decided not to put any more money into it. It sat vacant for several years and was bought by Universal Glass Co. In 1921 everything was sold off.

The area is owned by Valley Park and will become a holding pond when new flood walls are built. The EPA is requiring VP to clean up the area before and flood work is done, so it should be around for a while.


Walking through the area, it's amazing what is left. The old rock and concrete foundations remain along with the furnaces and tunnels where the molten glass would flow. Huge trees are growing out of the centers of the old structures. For those old enough to remember coal furnaces, notice that most of the area is crushed cinders. What looks like large 8-10' diameter rocks are actually "clinkers", formed after the coal has burned out and solidified.

The virtual cache is now a 1" diameter aluminum tag with "Geocache" and "Glass Factory" stamped on it. It will be easy to spot when you're in the correct area. Even if you can't find it, spend some time exploring the whole area.

There are several short and easy ways to get near the cache, but if you want a nice 3 mile R/T walk and a "tour" of the factory, park at the "Simpson River Walk" parking area on Marshall Road and take the trail/road. Just after you pass the parking area for the boat ramp, take the old dirt road into the woods. When you get to the boat, turn East and enjoy the area.
