Here is some informations about Gravel Fix Mod for Minecraft Frostburn that you can need before download it
This is very simple mod(well, barely a mod – just couple of lines of code).
Note: This mod will work even with texture packs. That means if you install both this mod and custom texture pack, gravel will have the old (1.2.5) texture (NOT the one from texture pack or from 1.3.1 vanilla). If you decide to use texture pack and you want TP gravel texture, simply delete this mod’s file
