The photo above shows slabs of Armorican Quartzite rising from Cíjara Lake (Embalse de Cíjara), near Cáceres, Spain. As shown here, Armorican Quartzite is formed of relatively light-colored, thick-bedded layers of quartzite or sandstone that may consist of gneisses, deformed tuff, arkose sandstone, and conglomerates. Cíjara Lake is actually a reservoir, a dammed portion of the Guadiana River, in the Toledo Mountains region of west-central Spain. Photo taken on May 23, 2016.
