#throwbackthursday to the Hoover Dam. A short drive outside of Las Vegas, this engineering marvel is well worth a visit. We took the hourlong Dam Tour that brings visitors into the power plant on the Nevada side followed by a tour within the 700+ foot concrete wall. The Hoover Dam is 100% self-sustaining and each of the 48 contiguous states contributed to its creation. #happygirldetours #hooverdam #gltlovetravel #glt #roadtrip #nevada #arizona #lakemead #nationaltreasure #exploreoutdoors #nationalhistoriclandmark #nationalhistory #ushistory
