|a Relatively few Holocene climate change studies in the Guatemala highlands have been completed. This study uses proxy records of climate change from Miqul Meadow, a high elevation (3147 m) site near Huehuetenango in the Sierra de los Cuchumantanes. Changes in vegetation and fire were reconstructed using pollen and charcoal from a sediment core dated ca. 12,000-2100 cal yr BP. Changes in forest taxa indicate that periods of drier climate were observable ca. 12,000-10,000 years ago, and later in the Holocene. Our results show that the climate was gradually drying around Miqul Meadow before the rise of the Maya in the lowlands. Pocos estudios sobre cambios climáticos del holocene han sido realizados en el altiplano de Guatemala. Este estudio utiliza datos por poderes de cambios climáticos para el prado Miqul, un sitio elevado (3147m) cerca Huehuetenango dentro de la sierra Cuchumatanes. Los cambios en la vegetación y la incidencia de incendios fueron reconstruidos utilizando el polen y carbón vegetal de una perforación de sedimentos datada a ca. 12,000-2100 años cal BP. Cambios en el taxa forestal indican que períodos de clima seca ocurrieron hace ca. 12,000-10,000, y aún más tarde en el holocene. Nuestros resultados muestran que el clima en la micro-región del prado Miqul estaban secándose gradualmente antes la subida de la cultura Maya en las tierras bajas.
