Acccumulated costs along Least Cost Path

Discussion created by wtgeographer on Jun 25, 2014
I am still a little unclear after reading the literature?

How does one determine the accumulated cost of all cells along a least cost path over a distance raster?  The attribute table of the path only shows the the source value of the the source cell from the distance raster.  This means that if another path even though longer and includes more cells in which overlay the cost distance raster  will always report the source value of the cost distance raster. How can I determine independent accumulative costs for both cost paths over the same surface?
