The classic Volcano of the North Cascades Mount Baker has the quality of routes like Rainier but without the altitude. The North 
Ridge of Mount Baker is a quality route with The Coleman-Demming an interesting glacier climb. The Easton is a more monotonous glacier route but is a good introduction to glaciated mountaineering. The Park and Cockscomb routes are more remote and more rarely done.
Routes on a glaciated peaks like Baker can vary greatly by the time of year. With good snow cover one can travel nearly anywhere without too much trouble from crevasses, but in a leaner snowpack crevasses may completely block certain routes. You will note 3 approaches to the North Ridge. The lowest is one I have used with the bivy marked on the map in September in very lean snow years. The middle one I have descended in September once but it seems to be a pretty good bet for most late season attempts. The upper route is the more common line for earlier summer ascents but was always out of conditions when I was there.
As with all the other posts in this series of North Cascades Maps I have a KMZ, KML, GPX and PDF for you, the links are below. I should give you a warning, the routes below might have errors and does not replace good route finding skills. Use at your own risk.
