Stream capture sequence in the Sierra de El Abra at a swallet (A), and subsequent stages of erosion of the sótano while the headwall on the old downstream side is left fairly unchanged. B is similar to Sotanito de Montecillos. C is similar to Sótanos de Jos, Yerbaniz, and Soyate except that the latter no longer takes much runoff. D is similar to Sótanos Japonés, Palma Seca, Tigre, and Venadito, E to Sótanos Pichijumo and Arroyo, and F to Sótano de la Tinaja, where one can walk into the cave during dry weather. William R.
