Though which plant we'll never know for sure but these 4 blobs of glass were dug near the site of the WGM plant back in the '70s though not by me. These were dug just a bit east and south of the plant not far from where present day I-25 and Alameda intersect. Three of the globs of glass are a deep amber and the one on the far left is a pretty smokey deep amethyst.
