I had the same problem, for the sake of anyone else who also has the same problem I will post the solution:

Upon speaking to the tree spirit, it creates a secondary quest that appears in the quest menu. To get a yellow marker leading straight to the horse and the remains just active the secondary quest "The Whispering Hillock" from the quest menu.

Happy hunting! :-)
