Giant Redwood Biome

BIG redwood trees (at least 5 blocks is diameter and 37 blocks tall.) There could be tall grass and podzol on the ground. It could be a neighboring biome to the big spruce. There could also be giant andisite boulders with cave pockets underneath exposing iron and coal ores. Another cool thing thing that would make this biome unique is a constant thick fog making it near impossible to see the treetops. This would be an exiting new biome to explore.
