The next Drunk on Geology post is for Rock Slide Organic Red another Glacier National Park themed wine by Ten Spoon Vineyard. They also released the Going To The Sun Pinot Gris posted about before.
Once a slope surface fails and the rocks start to slide, often additional material will then be knocked loose creating a larger landslide than initially started. Think of an avalanche (another type of mass movement event) where the amount of material at the beginning collects more material on its way down creating a massive movement of material.
Another great geologically themed wine from Two Spoon Vineyards.
