Work resumed early this morning on the Earth Shelter’s limestone patio. Installing the patio is somewhat similar to the installation of tiles- it requires level ground to place the stones upon, and once arranged, mortar will fill in the gaps. However, unlike the symmetry that can be expected from traditional square tiles, the limestones are eclectic in shape, size and texture. Some of the limestone rocks were artfully arranged by builder Hassan Hall in 2013, the work was continued by former summer interns. A small percentage of the patio, nearest to the shelter, were also previously mortared in place.
