Talk:Hawks Nest Tunnel disaster

Minor correction - Silica
I removed the first sentence of the "Silica" section. The tunnel was not mined for silica - it was purely for hydropower, and silica was not "discovered" - it was common knowledge that the local sandstone is largely composed of silica (quartz) and silica is not used in steelmaking (in fact, it is a waste product in the slag). — Preceding unsigned comment added by 152.180.11.47 (talk) 17:21, 25 October 2021 (UTC)
