The Finger Lakes Region was formed by the melting glaciers of the last glacial period, over ten thousand years ago. The northern and southern ends of the lakes gradually developed into extensive
marshes. First the Algonquin Indians and later the Cayugas of the Iroquois Nation were the earliest known inhabitants to reap the rewards of the bountiful life in the marsh. The name "Montezuma" was first used in 1806 when Dr. Peter Clark named his hilltop home "Montezuma" after the palace of the
Aztec Emperor
Montezuma in Mexico City. Eventually the Marsh, the Village, and the Refuge all acquired the name. There were no dramatic changes in the marsh until the development of the
Erie Canal in the 19th century, when it became apparent that feeder canals from
Seneca Lake and
Cayuga Lake would in time link these lakes with the main line. With canal construction, there arose the possibility of draining the marshes, and an act was passed relative to the draining of the Cayuga Marshes. Work first began on the canal system on July 4, 1817, and the completion was marked by the first passage from Lake Erie to New York City on October 26, 1825. Construction of the Seneca-Cayuga canal began in 1818 and by 1828 boats passed from Geneva to the Erie Canal at Montezuma. The Erie Canal did not greatly affect the marshes as the Seneca River still flowed directly from Cayuga Lake into the marshes. The refuge provides a stopping point for waterfowl and other migratory birds. The refuge restored marsh land lost to drainage from the construction of the
Cayuga and Seneca Canal that linked the
Finger Lakes to the
Erie Canal. In May 1973, the refuge was designated as the Montezuma Marshes
National Natural Landmark by the Secretary of the
Department of the Interior. On September 22, 2000, "Harmony With Nature"—an eight-person team of musicians from around the country—performed a four-hour, afternoon/evening concert at the refuge, featuring the music of the late
John Denver. The speakers and musicians/performers were: Pete Lee Baker, Tom Jasikoff (Montezuma NWR's manager), Tim Bak, Rob Bidinger, Val Cooper, Frank DeLaMarre, Paul Swanton and Brian Taylor (who also served as emcee of the event). Baker and Jasikoff conceived the idea for the performance, which developed into a series of "Harmony With Nature" concerts by the group, held on this and other federally protected land over 2000–2001 (four concerts in total, counting Montezuma NWR). This concert at Montezuma NWR marked the first time that a musical performance had ever been held on federally protected wildlife land. These musicians donated their talents and time by joining together to promote Denver’s legacy and to continue supporting his lifelong commitment to ensuring the preservation of the earth and all its natural habitats. The fundraising efforts also benefitted Montezuma NWR and the other wildlife sanctuaries, supporting and celebrating wildlife conservation efforts, ecological awareness, environmental education and habitat protection. Baker and Jasikoff also appeared in local, in-studio television interviews regarding the event. On September 24, 2017, another "Harmony With Nature" event was held there, with Rebecca Colleen, Bill Destler, Jim Clare and Perry Cleaveland providing a two-hour, afternoon music show at the refuge. == Conservation management ==
