Blanca Aili Usuga was chosen to be featured in the Extraordinary Women Cavers Guidebook and Magazine for along side several other extraordinary women cavers in the 2017 August release of the annual publication. Blanca became a member of South Wales Caving Club in 2010. In 2012 she found two unexplored Colombian caving areas called Mortiñal Cave System and the Valley of Deep Holes containing more than twelve sinkholes and caves. Blanca organized an international expedition in 2015 to explore the sinkholes that resulted in the survey and mapping of nine caves - a total of 2046 meters of virgin cave systems. She has proposed the creation of a nature reserve and speleological park that is under way in each area. Welcome Blanca and congratulations on becoming an EWC! Photo by Josh Bratchley
