USCGC Mesquite WLB-305

USCGC Mesquite (WLB-305) was a 180-foot Iris-class buoy tender commissioned by the United States Coast Guard in 1943. Throughout World War II and the following decades, Mesquite performed vital aids-to-navigation, search and rescue, and icebreaking operations primarily in the Great Lakes region. The vessel also contributed to law enforcement and environmental protection missions during her service. On December 4, 1989, Mesquite ran aground off Keweenaw Point, Michigan, and was subsequently deemed unsalvageable and abandoned; her wreck now serves as a popular dive site.
