Need help finding path BAD

I can't find the sunken ruins cliff texture anywhere. Could someone please help me find it. I found the regular ground texture but not the cliff.
Help! :(

maybe typing cliff in wc3viewer will that do anything?

in wc viewer, u have to open the wcx.mpq (expansion)

I know which mpq to open. I tred cliff, wall, ruin etc looked and looked didnt see anything that looked like wall textures.
God damn i need so bad. i'll give points to who ever finds it.
