If you browse through old photos of Yellowknife’s Old Town you will see that the land that Old Town sits on has actually expanded over the years. The ball diamonds and the Air Tindi Float base use to be wet swampy areas until they were filled in with gravel and fill.
Float Planes for the first form of access to Yellowknife and supplied the community and the economy with materials and food for many years, especially when the barge could not get to Yellowknife. If you drive through Old Town today you will still see many Float Planes and they are still a big part of small exploration projects and transportation between the many lodges and camps around Yellowknife.
If you haven’t been on a float plane, you should really take a sight-seeing tour sometime.
