>Denver AP Built by THE Masons call to dig
Haven't seen this mentioned, but there's a plaque written in braille above the time capsule capstone.
Found a possible translation, working way through confirmation now.
The inscription does end with 2001. VERY ODD, especially when that year is not written on the capstone itself.
