Our history

The Peter Russell Rock Garden, originally called The Geological Garden, was established by museum curator Peter Russell in 1982 to commemorate the 25th anniversary of the University of Waterloo.

Founding President J. Gerald Hageyon announced the project on January 8, 1982, and the university’s application for funding was accepted by the Canadian Geological Foundation in 1984. The project was made possible through these funds along with contributions from Wintario and a bequest in memory of University of Waterloo alumnus, Malcolm Heaton.

The search for what was intended to be the first 12 rocks began in 1986. Rocks were collected from locations across Ontario, including St. Joseph Island in Georgian Bay, Marathon, Bancroft, Sault Ste. Marie and Timmins. The Earth Sciences department officially opened the garden on May 29, 1987 with 23 rock specimens representative of several different geological formations found in Ontario.

Of these original 23 rocks, the most difficult to find and collect was the Jasper Conglomerate. To retrieve it from the bottom of a quarry, geologists needed a crane, truck and trailer, all of which became trapped in the soft sand. They were rescued using a cable from a driller’s truck attached to the quarry’s front-end loader, which pulled them all free – along with the rock!

Peter with the Stromatolite Marble

Stromatolite from Thunder Bay. Wayne DeBrusk of Shuniah Twp. near Thunder Bay has donated a wonderful example of stromatolitic limestone, originally from the Eaglehead Lake area north of Thunder Bay. This one was found in a gravel pit. Strom as Wayne calls it is installed in our rock garden.

In the summer of 1999, the Geological Garden was renamed the Peter Russell Rock Garden in recognition of Russell’s contributions to the university.

Three new rocks were installed in his name that same year. Russell came to the University of Waterloo in 1967 to work as a lab technician and later took on the role of curator at the Earth Sciences Museum. He retired in 1996, but continued as curator until 2012, when he became curator emeritus.

Since it opened with the original 23 rocks in 1987, the Peter Russel Rock Garden has become a new home for more than 80 specimens, and the collection continues to grow. It’s enjoyed by elementary and high school students and other community groups interested in learning more about geology in Ontario. The garden rocks are also used as learning tools in Earth and Environmental Science courses and laboratories.

Visit the garden and enjoy the relaxing atmosphere or share your lunch break with the resident squirrels. It’s a peaceful place to appreciate the outdoors amidst the hustle and bustle of the work or school day.
