Pressure ridges, the barriers to travel over the
Arctic ocean. One of the hardest things the team had to do was get over the 20 to
50 foot high ice barriers called
"pressure ridges". These are formed when the ice buckles under
force from wind, tides, currents and is thrust up. They are hard to
get over as you can see here in this picture.
Often the heavy sledges had to be unloaded, supplies carried over,
dogs brought over and then everything packed back on only to repeat
this several times a day at each new ridge.
This black and white photo was hand colored by the publisher for
printing in Peary's book. The North Pole contains 5 such
colored prints. |
