Square cut nails and wood pegging were used to join areas. The flooring is pine. Chinking of the wall logs was done with clay, horse hair, and bark. Immediately upon entering the Southwest Texas area, one notices a relatively flat area interrupted by low growing shrubs, Yuccas, Cacti, and other dry climate flora. The common plants represented in the area are Mesquite, Huisache, Cenizo, Blackbrush, Guajillo, Ebony, and Sotol.
Wildflowers abound in the spring.
The Southwest area has two adobe structures. One is a palisado-adobe building with a split shake roof. Constructed of materials salvaged from an old palisado home on Culebra Road, the structure was originally built in the late 1800's and is similar to some still found in the San Antonio area. Sections of wall space are left exposed to illustrate the different methods and materials used for chinking the open spaces between the vertical posts. Lathing of sawed strips of wood or twigs were fastened horizontally for added support.
