The Cascades Proposal for the Deep Underground Science and Engineering Laboratory [PDF]
Nuclear Physics B - Proceedings Supplements, 2011 One of the options for creating a Deep Underground Science and Engineering Laboratory (DUSEL) is a site in the Mt. Stuart batholith, a granodiorite and tonalite rock mass in the Cascade mountain range in Washington State. The batholith's 100-year history in hard-rock tunneling includes the construction of the longest and deepest tunnels in the U.S ...
