Before you visit: check what facilities/activities are available and pack what you need (e.g. water, snacks, mask/face covering, and hand sanitizer). Postpone your visit if you have any symptoms of COVID-19 or have been asked to isolate.
When you visit: Continue to follow public health advice including practicing physical distancing by keeping at least two metres from others, wearing a face covering where required, when physical distancing may be a challenge or not possible and when entering indoor public spaces, and wash your hands regularly with soap and water or use alcohol-based hand sanitizer if soap and water are not available.
Geologists will find Thompson Island interesting for its Paleohelikian gabbro dikes and sills, formed approximately one billion years ago. These dikes and sills were created when pressurized volcanic lava deep within the earth’s crust was thrust through vertical and horizontal crevices in the bedrock. The lava or magma hardened into gabbro, a coarse-grained dark rock. The nature reserve also features raised cobble beaches, and Arctic-alpine vegetation growing at its most southerly limit.
Location: In Lake Superior south of Thunder Bay.
