Located on Indonesia's island of Java, the Bromo-Tengger-Semeru National Park lies within an active volcanic region.
One of the calderas, Gunung Bromo (named after Brahma, the Hindu God of Creation), is near constant active - venting steam & sulphuric gases with occasional incandescent material. The latter results in a rain of ash which falls and builds upon a plain within the enclosing Tenggar Caldera. This plain is known as the Sea of Sand.
Crossing the sea is a cumbersome task, through thick soft choking dust, to reach the fertile slopes on either side of the ancient Tenggar Caldera where, on the northern & eastern flanks, crops grow in abundance and, to the south & west, rain-forest stretches across and beyond to Mt Semeru. The plants on all sides enjoying fertile fresh nutrient-rich volcanic soils.
These photos were taken a few months after an unusually active period, when a month of continuous eruptions resulted in a prolonged fresh ash fall.
