This peninsula is among the farthest north of Canada's mainland, and in another era seemed to be scoured and …smoothed on its right side by active sea ice. This had prevented the mid-sized Horton River from entering the ocean until near the tip of the peninsula. In more recent conditions the river has broken through the coastal bluffs to form a new delta, leaving moribund the final 75 km of its previous course. Small clusters of sea ice drift offshore to remind us of these changes.
