    Are there any restrictions on material?

    If not, I have stack of dirty nitrogen in my backyard over 100km tall, technically reaching space.

      I’m pretty sure anything physical referred to as a pyramid would have to keep its shape, and therefore must be a solid.

        That makes sense. Though at geological scales the distinction between solid and non-solid blurs a bit. Mountains are not solid to a slow enough observer.
