NHL status and 1980 and other For reference here is a NRHP infobox fresh from the Elkman supported generator system NHL status was claimed in the article without a link to support usually provided I can t find this in the National Park Service s webpages on NHL properties and districts so am removing from article as an apparent error Please comment if you have any different information Also there was a 1980 date in the infobox in the article I removed that too as I can not find what it was referring to Was this district designated in some state or local program in 1980 possibly
