Vulcan Concepción, Isla de Ometepe, Nicaragua
Towering 1610 meters up from gigantic Lake Nicaragua, this is one of two volcanos on the small island of Ometepe.
Concepción, being the taller of the two, is a more difficult climb--and as seen here, often generates it's own weather system starting at about 1000m. Climbing the vulcan starts near the base of one of the islands main towns, Moyogalpa, and while the weather may be sunny and clear at the base and the path easily accessible, the story changes the higher you go.
Once you work your way thru the initial stages, the path begins to climb vertically--and fast. Working your way thru dense foliage and lush jungle, you'll occasionally spot coffee beans and howler monkeys. Get up around 1000m, and you find yourself in a completely different place on Earth--a foggy, extremely windy, and desolate landscape with only small shrubbery to crouch behind in between gusts of wind.
Since 1883, Concepción has erupted at least 25 times; its last eruption was on 9 March 2010. Concepción's eruptions are characterized by frequent, moderate-sized explosions, and active fumaroles are present just north of Concepción's summit crater.
