Montaña Blanca is a nucleus that belongs to the municipality of San Bartolomé, and is located between two mountains, Montaña Guatisea and Montaña Blanca. It owes its name to the 590 m high peak of Montaña Blanca which dominates the southeastern part of the island.

Large hydraulic works were developed on both Montaña Guatisea and Montaña Blanca to make the most f the water runoff, with reservoirs able to store it. They consist of open ditches on the slopes to catch water and pipe it to the so-called "maretas" in which it is kept, after it has gone through "coladeras" to remove sediments. By this system the population of Tias was provided with water from Montaña Blanca, and the population of San Bartolomé was provided from Montaña Guatisea.

San Bartolomé

The village of San Bartolomé occupies a central position on the island, and is one of the most dynamic municipalities in terms of population growth. It has been traditionally characterised by its agricultural importance, above all by the production of sweet potatoes in the "el jable" (giving the towns inhabitants the nickname of the batateros – sweet potatoes), and of wine in La Geria. Besides, there are areas of land dedicated to the cultivation of pulses, cereals and vegetables around the village. Stockbreeding, mainly goat and sheep farming, is an important activity.

Ground in this area is covered by sands of organocenic origin, which cross the island from Famara to the southeast coast. A peculiar and important growing system has developed, taking advantage of these sands, which help to maintain ground humidity and temperature and avoid runoff. In order to develop this growing system windbreaks made from cereals are used, called "bardos", to protect the crops from wind.
