  In the west of the country, these lowlands consist of a broad, hot, fertile plain. Punctuating this plain are several large volcanoes of the Cordillera Los Maribios mountain range, including Mombacho just outside Granada, and Momotombo near León. The lowland area runs from the Gulf of Fonseca to Nicaragua's Pacific border with Costa Rica south of Lake Nicaragua. Lake Nicaragua is the largest freshwater lake in Central America (20th largest in the world), and is home to some of the world's rare freshwater sharks (Nicaraguan shark). The Pacific lowlands region is the most populous, with over half of the nation's population.
  
  The eruptions of western Nicaragua's 40 volcanoes, many of which are still active, have sometimes devastated settlements but also have enriched the land with layers of fertile ash. The geologic activity that produces vulcanism also breeds powerful earthquakes. Tremors occur regularly throughout the Pacific zone, and earthquakes have nearly destroyed the capital city, Managua, more than once.
  
  Most of the Pacific zone is tierra caliente, the "hot land" of tropical Spanish America at elevations under 610 metres (2,000 ft). Temperatures remain virtually constant throughout the year, with highs ranging between 29.4 and 32.2 °C (85 and 90 °F). After a dry season lasting from November to April, rains begin in May and continue to October, giving the Pacific lowlands 1,016 to 1,524 millimetres (40 to 60 in) of precipitation. Good soils and a favourable climate combine to make western Nicaragua the country's economic and demographic centre. The southwestern shore of Lake Nicaragua lies within 24 kilometres (15 mi) of the Pacific Ocean. Thus the lake and the San Juan River were often proposed in the 19th century as the longest part of a canal route across the Central American isthmus. Canal proposals were periodically revived in the 20th and 21st centuries. Roughly a century after the opening of the Panama Canal, the prospect of a Nicaraguan ecocanal remains a topic of interest.
  
  In addition to its beach and resort communities, the Pacific lowlands contains most of Nicaragua's Spanish colonial architecture and artifacts. Cities such as León and Granada abound in colonial architecture; founded in 1524, Granada is the oldest colonial city in the Americas.
