The Ecosystems
of Lake Ennis

As glaciers rolled across the landscape of Northeastern Minnesota, they left enormous ice boulders in their path. As the glaciers crept past, these enormous boulders remained, leaving an impression in the land and melting to form lakes. Cuts like these are what caused Lake Ennis.

Lake Ennis is located about ten miles out of Ely, Minnesota, which is only about a half an hour drive from the Canadian Border. It is the last lake located on the Secret/Blackstone trail, being created by a glacial cut has created this unique ecosystem. Much of the soil has been filled with rich nutrients. Walking along the trail one can see a diversity of trees, from coniferous pines to deciduous paper birch. The forest environment is strong and stable due to reduced usage and protective measures by the DNR and forestry service to keep the trail natural and wild.

The soil filled by glacial till is very rich. The adequate resources provide an amiable environment for vegetation to grow, encouraging such animals as beavers and trout to flourish in the lakes and wetlands. Along with this marsh ecosystem comes the environment of rocks and bluffs. The granite bedrock formations line the shores of the lake providing its visitors with an amazing spectacle and view of the forest. The formations also attract climbers, repellers, and hikers. The smooth faces and jutting out ledges provide the perfect environment for classes such as Outward Bound to teach mountaineering skills.

Despite being engulfed by rock, plants are able to survive. Lichens are a common occurrence all over the rocks. Lichens are a symbiotic pairing of algae and fungi. Algae provides the lichens with food production and fungi anchor the lichen to the rock and break the rock down to supply nutrients for the relationship. Pines loom large over the cliffs as they have worked their way through cracks and crevasses to establish a foothold on the bluffs. The cliffs are suited for many small creatures as chipmunks and squirrels dance dangerously around the edge and birds fly high and nest in the trees.

With a solid rock base, the Lake provides some of the clearest water around. Being as pure and natural as it is, the lake is perfect for a freshwater ecosystem as plants line the shores and trout fill the water. It acts as a watering hole as deer come to drink and beavers to work.

One can sit atop their choice of the great cliffs and see a beautiful reflection in the lake as the sun sets on another day or they can wake up to the mist or the water from a beautiful sunrise. With life everywhere and water flowing freely through the circle of life, Lake Ennis is perfect example of many ecosystems working in perfect harmony.

With the populations of beavers and birds that inhabit the wetland areas of Lake Ennis, a unique marsh ecosystem is created. Looking entirely different from the rocky cliffs and bluffs that surround the lake, this marsh is a habitat that can support numerous species of waterfowl, mammals, and wildlife. It adds even more color with its green plants to the already rich environment of the ecosystem.

With a bedrock base, the water is some of the clearest and cleanest around the Minnesota area. Without silt, sand, and clay suspended in the water, the water is crystal clear and blue as the sky. Rocks can be seen as they taper off down into this deep lake. The shoreline is amazing as you step off into areas with a depth of 20 or more feet just a few yards away from the shoreline. Along with the great cliffs surrounding this deep lake, Ennis is one of the few safe spots where individuals can overcome their fear of heights and take an amazing cliff dive into this cool Minnesota lake. With dives from 20 to 50 ft., Lake Ennis is the perfect spot for the beginning or expert thrill seekers. One can look off a cliff into the deep blue water before taking that exhilarating step of the ledge and into a free fall towards the surface.

The cliffs of Lake Ennis have become a common spot for sport climbers and recreational climbing. Its straight flat faces and gentle grades provide excellent areas for the novice repeller and climber. Despite having such elementary climbs and repels, Ennis does have some of the more challenging climbs of the area. This spot has increased in usage over just the last three years and is becoming a mainstay for the Outward Bound program and other outdoor adventure classes
