Although I can’t give you info on Bear Pass over to Olympus, I did do the Bailey Range in ’05, avoiding Cream Lake like the plague. Here is the WTA trip report (Including photo links) which describes the method to avoid Cream Lake on day #4:
The specific route had previously been described to me by another CC member:
“The trick is to cross over the ridge before it makes a big left turn:
From the catwalk you walk below the main SE trending ridgeline. Go past 11-Bull Basin, and the trail eventually takes a sharp left at the corner, to the east. This is the major ridge at peak #5988. There is a minor ridge (WSW trending) just before that corner. You are on a well worn path in a large talus field when you see that minor ridge. The minor ridge line has trees along its spine, except for a gap near the top. On the topo, the top of this ridge gets to a large flat area. Your destination will be there, at peak #5796 on the older USGS map.
Now here's the part where many people have a hard time. Leave the well worn path that seems to continue forever and instead aim for that gap up in the tree line at the top of the minor ridge. Work your way up the steep but grassy cirque bowl to the obvious treeless gap. From there a game trail gets you the last 100-150' to the top (flat area, good camping, there's generally snow and water in a depression up there), then cross the major ridge to the east and look below to Stephen lake (big lake NW of Stephen Pk), or preferably tarns above the lake, warmer for swimming. Scramble down the loose talus from here and cross N, just above of Stephen Lake. Then climb up a gully system to NE of Stephen Pk.. (easy scramble to summit if so inclined), continue around the E shoulder of Stephen Pk, staying at about the same altitude if you can. Cross a couple of snow and rock fields as you head south, until you reach the ridge on the south side of Stephen Pk. From there simply walk along the ridge line game trail until you can find “easy” descent into Ferry basin in about a mile when the game trail ends at a cliff face.
Another way is to ascend Carrie and then traverse the ridgeline all the way to the flat area mentioned above. I've never done it all, but did come back from the flat area to Ruth Pk (along the ridgeline) once. Viewed from Carrie summit, the traverse from Carrie to Ruth looked easy.”
