The north slopes definitely do go at 2+. The only remotely tricky part is just below the false summit, the rest is a walk. Stay dead center below the bulge - left or right is steeper and the ledge systems thin out.
Finally... after my 3rd trip up North Guardian Angel. We were down by 10AM, and faced a boring day at camp unless we did something! So it was this peak(from N), then Oscar's in Springdale, then beer & wine at a BLM primitive site.
