Abstract
Gunung Kendil is one of the karst hills located in the district of Ponjong, Cunung Kidul regency
(8"00'56.64"5, 110o44'18.32"E). This hill is situated approxirnately 400 meters north of Ponjong
District and about 20 km east of Yogyakarta.
Gunung Kendil is composed of bedded-limestone in the bottom par1, chalky limestone, massive
limestone with conduits, and reef limestone at the top. These rocks are included in Wonosari
Formation, which is formed in Middle Miocene age (10-16 million years).
Groundwater system beneath Gunung Kendil is controlled by fractures, faults and bedding. The
normal faults below Gunung Kendil are northeast-southwest trending almost facing each other
forming a large subsidence. Cross cutting of the two normal faults and the bedding that is gently
sloprng to the nofth beneath Gunung Kendil fonn an underground river flowing toward the southwest
and out as springs at the front of the Village Ponjong, called Urnbul Ponjong (Surnbergiri)
(7o 58', 34.39"S, I I 0o44',06.89"8).
The spring is very beneficial to people's lives in the village of Ponjong. At this time Umbul Ponjong
already managed by the Regional Government of Gunung Kidul as a unique and interesting tourist
area and geological heritage.
Key words: Gunung Kendil, groundwater system, fault, Umbul Ponjong
