My wife and I first attempted this a few years back, but only got to within 1/2 mile of the summit and I did not want to leave her at the car. We returned on 7/10/2021 so I could get this fairly easy first activation.
The forest service roads are easy to follow to and we parked at 48.8231, -121.9244. A motorsycle might be able to drive closer to the summit.
The 1/2 mile to get up was 400' in elevation gain. I started out too quickly and had to ratchet it down. I foloowed the road to the end and then traversed to the summit.
I was able to garner two summit to summits, with a total of 11 contacts on 2 meters. Many were Canadian ham contacts....
This might be doable with North Lookout Mountain. The activation that has occurred there so far was on snowmobiles and it is presumed that there is about 1500' climb, if done in the summer...
