North Fork, " The Black Canyon"

I was curious if anyone nows how to access the Black Canyon portion of the North Fork of the Snoqualmie? I had the chance to hike on the ridge above it today and was going to attempt the steep climb down but decided not to risk it. If there is anyway to access this portion of the river without crossing private property it would be greatly appreciated. I live on the South Fork but I have heard some good folk lore about the Black Canyon, you can mail me at [email protected] if you want to keep directions private. Thanks!!!
