We looked up. There. A sliver of dark cloud clawed its way down towards the forest canopy just above the crater. We became quiet. For a while it hovered as if waiting to strike. Silence descended upon us. We were still. Unmoving like the rocks we sat on. We only stirred when the menacing dark cloud slowly dissipated in thin air. Then we gathered our things and left…. gently, with only our eyes talking. It seemed that if we tripped on the tree roots and stumble, the lake will open up and swallow us alive.
