I am reading up on the French and Indian wars. It is hard to think of Northern NY State
as a rugged wilderness. However, the stretch between Glens Falls and Pattsburgh is still untamed and rugged. Today the area is known as Adirondack Park and it is not easy to cross with modern materials such as goretex and with insect repellent.
What makes all of this interesting is that there were plenty of people who had experience in this area in the 1750's. General Burgoyne marched through this area of swamps and thick woods for no known reason. He could easily have floated down Lake George and kept his forces in tact. Instead he decided to go over land where a few men with axes could delay armies. The colonials tore up bridges and flooded roads in places as well.
The rest is history.
