A polar bear is the creature that comes to mind as well equipped to travel across icy cold open water, and frozen ice surfaces, with its excellent swimming and claws for climbing up onto the ice.
With a $300, 20-lb inflatable Aqua Marina Fusion stand up paddle board, a $300 dry suit from
www.mythicdrysuits.com, a paddle, a pfd, feet ice grippers, and hand ice spikes, a determined paddler could go from land to ice to water to ice to land. Include a cup of hot coffee in a paper cup and you are good to go! ...
This paddle board has a recessed handle at its center and at just 20-lbs makes its easy to hold it under your arm while walking along and carrying it or towing it on a bow line across the ice. It is 10'6"x 32" x 6" and very sturdy design.

And, here's a different method ...... by flying! Yesterday, Oct 6 in the mid-afternoon, heard and saw a small black helicopter that supposedly lives somewhere out on Bear Island ....... an enclosed, long distance helicopter that could cost maybe $150,000 or some unknown amount ..... capable to commute from Acton MA to Meredith NH.
