The mixture of red and golden-yellow colours of the deciduous trees in the fall is the most observed annual natural phenomenon in northern Ontario.
Limberlost, with some of the highest elevations in the region, looks out over hundreds of kilometres of forests. As a result, excellent vantage points can be found on the property to view the landscape as it turns from green into bright reds, yellows and golds in October and November of each year.
The top of Echo Rock and the cliffs on the west side of Buck Lake provide the most stunning lookout sites. From there you can look east and south over the lakes to view the green coniferous trees contrasting with the birches and maples, rising up to the top of the surrounding hills.
The weather conditions leading up to the fall months determines the vibrancy of the colours that will show.
Each variety of tree has its own distinct colours, however, the green pigment from the chlorophyll in the leaves is the most dominant. Without the green chlorophyll the process of photosynthesis would not occur, which is critical for the production of sugars to provide nourishment for the trees.
Cool fall nights and warm, sunny days mean that the trees are unable to use all the sugars produced in the leaves. To avoid a toxic overload of sugar, the trees produce a chemical called anthocyanin, which creates the red and purple pigments in the leaves of red maple, mountain ash and flowering dogwood.
Overcast days and warmer nights will dim the display of colour, as will early frost, which often causes black spots to form on the leaves.
The crests of the old Limberlost ski hill and Millar Hill are also excellent places in the region to enjoy the spectacular fall colours.
