Maple Canyon: climbing in the wet?

I assumed Maple Canyon is a no-go for wet weather (sandstone/conglomerate) but am I wrong?

Those cobbles will be desperately slippery when wet.

Doesn't matter. But it sure won't be pleasant to climb if wet. 

Plenty of routes and crags that stay dry in rain. Bumber, bridge, Zen, craggenmore, minimum, pipe dream are a few. Maybe not all routes but enough. 

The cobbles are quartzite which will be fine, 

The matrix varies from soft sandstone to bullet-hard quartzite.

Assuming the matrix is then indeed weakened by moisture? 

Sorry I should have been more clear.  It varies from area to area more so than it does from route to route, ie, some crags are unfazed by water and others might be a problem.  

For more established crags (older crags historically), I suppose more comments about choss means more likelihood of a sandstone matrix?

But I'm kinda theorizing here.  Anyone want to geek out and make a spreadsheet on the issue?  

Bottom line, just stick to the crags that remain dry in the rain and you'll be fine.
