In 1974, Dinosaur Hill Nature Preserve was formed to provide hands-on educational experiences that encourage knowledge of and appreciation for the natural environment through a collaborative effort of the City of Rochester, Rochester Community Schools, and concerned residents. A 16-acre parcel of land in a developing subdivision was identified as ecologically significant, with many different habitats along the banks of Paint Creek. On November 16, 1975, the Rochester Community House was dedicated after a log pavilion built at the former Avon Park following its 1935 dedication had been expanded and improved over the years. On February 3, 1977, the first meeting of the Rochester Historical Commission was held, beginning its mission to protect and preserve Rochester's historic and prehistoric resources for the use, education, enjoyment, and economic benefit of present and future generations.
