About

Join Dr. Soren Brothers, the Allan and Helaine Shiff Curator of Climate Change at ROM, for an exclusive ROMBus day trip to Crawford Lake near Milton, Ontario. As you walk the lakeshore with Dr. Brothers, you’ll learn more about how the sediments beneath this quiet lake record humanity’s changing impact on the planet and inspired the original ROM exhibition Crawford Lake: Layers in Time.

The lake began to reveal its incredible story in 1970, when ROM curator John “Jock” McAndrews launched a research project there to study how 19th-century European settlement changed southern Ontario’s forests. More than five decades later, Crawford Lake made global headlines when an international team of scientists identified it as the best place on Earth to reveal evidence of humanity’s planetary impact.

Following the lake walk, we’ll enjoy lunch at Campbellville’s Risposta Italian Bistro before visiting a reconstructed 15th-century Wendat or Attawandaron village. Based on excavated foundations discovered in the 1970s, the village’s longhouses, artifacts, and living spaces bring to life the culture and daily life of the Indigenous communities who once called this area home.

Dr. Soren Brothers

Dr. Soren Brothers is the Allan and Helaine Shiff Curator of Climate Change at ROM. He is also an Assistant Professor at the Department of Ecology and Evolutionary Biology at the University of Toronto. His research has focused on the effects of climate change on lakes, and how changes in aquatic systems can influence their greenhouse gas emissions into the atmosphere.

Originally from Toronto, he has worked on lakes in a diverse array of environments across Canada and around the world, including Nunavut’s tundra, hydroelectric reservoirs in Quebec’s boreal forests, and the Great Salt Lake in Utah. Soren joined the team of researchers working on Crawford Lake in 2022. Since then, he has acquired lake sediments for ROM and has begun to carry out original research. A passionate science communicator, he has led many tours with both students and professionals at Crawford Lake, and is lead curator on the ROM original exhibition, Crawford Lake: Layers in Time, which continues until September 2026.

Highlights

A globally significant research site: Scientists from around the world—and thousands of students each year—visit Crawford Lake to study its astonishing scientific record.

A remarkable discovery beneath the lake: Sediment cores from the lakebed revealed a significant layer of corn pollen dating to the 13th century—evidence of early agriculture and a powerful clue to the lives of the Indigenous communities who once lived here.

Indigenous art and archaeology: One of the reconstructed longhouses features an Indigenous art display alongside remarkable artifacts uncovered during the archaeological excavations.
