C4F,
Inspite of the trashing the Mt Adams North Ridge has taken on this board for being 'miserable, despicable, in-obvious route-finding', I did it in July, up and down. When I went it was all rock except for the summit snow cap. You shouldn't need any rope/pro. Crampons would only be needed (doubful) on the summit cap, but the slope is very mild. We did not put on crampons. Reflecting back, I feel the board was right. The next time I'm on it will only be as a descent for another route.
However as you can see Vancleav enjoyed it a lot, so this is only one person's opinion.
We did see a herd of goat's a couple of times and exerienced great views of the Adams glacier and Lava Headwall.
Good luck!
