Some that I would like to do.
Canol trail from Ross river Yk to Norman wells Nwt. Last time known completion in Jeep was about 1970. Lots of attempts of lately, most people run out of time. Land rover club almost made it to the twitya river. Some local toyota guys trying as well as some local bike guys trying this summer. Time frame, two weeks to months to complete? style Bring your own boat to get your jeep back.
Second would be the old highway from Mayo Yk to Eagle plains Yk. Build by the oil companies to bring drilling supplies in to eagle plains in the early fifties. Used for a couple of years then abandened when the goverment build a road to Inuvik a couple years later.
And an easy one. Take the old highway from Slave Lake ab to Grourod (sp) ab. It goes around the north shore of Lesser Slave lake. Abandened in late forties? Did part if it. Time frame couple of days to a week.
