In such a rough landscape you feel somewhat out of place. The slow streaming of the lava gave rise to rough surfaces. A rapid drop of temperature of the molten rock may produce irregularities and clefts. Besides gray and black as a prominent colour, yellow-greenish surfaces may also draw your attention.
When the flow of molten lava is slow they also form rather smooth surfaced and large rocks with obvious stratification. Large grooves occur between these masses.
The air bubbles trapped within the molten lava create spaces of varying size; from microscopic to miles long volcanic caves. Do you see the laminar formation of the volcanic mass?
