The Dyer Memorial (1956) sits in a clearing within the Dyer Memorial Nature Reserve. It can be reached by car, about 2km from Williamsport Road. The monument was erected by Detroit industrialist Clifton Dyer as a memorial to his wife, Betsy Brown Dyer. The couple first came to the property on their honeymoon in 1916, and continued to visit through their marriage. Following her death in 1956, the monument was erected as a resting place for both of their ashes, and the property was made public and operated by the trustees. It is now maintained by the Muskoka Conservancy. 

The Dyer Memorial is a coursed stone, square tower that tapers slightly as it rises. It sits atop a coursed stone platform with a centre plaque, has two square stone projections near the top, and a tapered rectangular projection just above and between the square projections with a plaque that reads

 “ERECTED IN FOND MEMORY OF BETSY BROWN DYER 1884-1956 BY HER HUSBAND CLIFTON G. DYER 1885-1959 AS A PERMANENT TRIBUTE TO HER FOR THE NEVER-FAILING AID, ENCOURAGEMENT AND INSPIRATION WHICH SHE CONTRIBUTED TO THEIR MARRIED CAREER AND AS A FINAL RESTING PLACE FOR THEIR ASHES.”
