i remember driving past it, i didn't climb it

i'm of the opinion that there definitely is some structures that due to the climate of the region got weathered to hell and are deeply collapsed to the point where you'd have to burrow through the entire structure to find parts that are still remnant

it's hot up there in north queensland, i can't imagine that a giant pile of bricks stacked in a pyramid made out of synthetic stone would not look like a mountain after 8000+ years
