Abstract. Calcareous mountainous areas are highly prone to geohazards, and rockslides play an important role in cliff retreat. This study presents three examples of failures of limestone cliffs with subhorizontal bedding in the southwestern calcareous area of China. Field observations and numerical modeling of Yudong Escarpment, Zengzi Cliff, and Wangxia Cliff showed that pre-existing vertical joints passing through thick limestone and the alternation of competent and incompetent layers are the most significant features for rockslides. A "hard-on-soft" cliff made of hard rocks superimposed on soft rocks is prone to rock slump, characterized by shearing through the underlying weak strata along a curved surface and backward tilting. When a slope contains weak interlayers rather than a soft basal, a rock collapse could occur from the compression fracture and tensile split of the rock mass near the interfaces. A rockslide might shear through a hard rock mass if no discontinuities are exposed in the cliff slope, and sliding may occur along a moderately inclined rupture plane. The "toe breakout" mechanism mainly depends on the strength characteristics of the rock mass.

Ceramics are one of the key diagnostic artifacts that define the Late Prehistoric culture of the peoples that lived along the East Fork of the Trinity and its tributaries. We are completing a 42 year re evaluation of the Late Prehistoric period of the area and have st udied nearly 32,000 artifacts, of which over 10,200 are ceramic sherds. From this study, 20 distinct ceramic types have been recognized. Plain ware, both shell tempered and sandy paste/grog tempered, are the predominant ceramic types present, comprising ov er 90 percent of the total ceramic assemblage. While there is little direct evidence for indigenous manufacture, the abundance of these types suggests they were produced locally. Lesser quantities of decorated ware of distinct Caddo ceramic types from the Red River and East Texas suggest they are likely the product of exchange. There is also a small amount of Puebloan material indicative of a longer distance exchange.
