Once the boulder is prepared and the mount is finished, installation at the Museum is ready to begin. The floor of the exhibition hall must be reinforced to hold these massive weights. When the floor is ready, the boulders (already on their new mounts) are transferred to a flatbed truck and shipped to New York City for installation in the Gottesman Hall of Planet Earth. Here we see a boulder attached to its mount, lying on its side, being rolled in to the hall by riggers.

To move these massive boulders and mounts into place, the installers have laid I-beam rails, and the massive samples are rolled into place on logs. Once in place, they are righted with the help of ceiling-mounted winches. Due to the immense size of many of the specimens, they must be installed early on while much of the hall's construction continues around them.

Surrounded by construction lighting and cable, this boulder of obsidian rests in place upon its mount. A neighboring sample, a large mafic bomb also from Medicine Lake Volcano, has not yet arrived.
