Steep and flat is an excellent Black Diamond run.
Here's how to find it.
From the Top of the World Express head down either Homerun, the trees on Homerun's left or the Sunset Chute.
Head to the left hand side of the ridge of Grizzly Gully.
Ascend the ridge and scope your options along the way.
You can either surf the side of the ridgewall or commit to a line from the top.
If this area is fresh it's an incredible run.
In shoulder season it tends to be bare, with some sharks, etc.
Descend into the Grizzly Gully and to your right hand side will be the Top of the World Express.
Be sure to check out the observation platform with the incredible view of Lake Louise and the Bow Valley.
This is a great area for photo op.
