Do you have your ridge data as a tin? You could create another tin by digitising a few points around the upper and lower sides, and with a bit of math, make it have a ~5deg slope. Then use Surface Difference—Help | ArcGIS Desktop  to get the volume. ... View more

If the 2 list of features and rasters sort in the same order you could make a zipped list like this. >>> rasList = ["Ras01", "Ras02", "Ras03"] >>> fcList = ["Fc01", "Fc02", "Fc03"] >>> zipped = zip(fcList, rasList) >>> zipped [('Fc01', 'Ras01'), ('Fc02', 'Ras02'), ('Fc03', 'Ras03')] >>> ‍‍‍‍‍‍ With the 2 lists being created by ListRasters & ListFeatureClasses in each workspace.

Well, maybe with windows updates, sometimes it does . But, most times it revolves around the operator So I suggest you carefully review your project structures, get the data organised properly - fgdb's for example.
