    A Look at the Texas Hill Country Following the path we are on today through 2030 This unique and special region will grow, but what will the Hill Country look like in 2030? Growth of the Hill Country The Hill Country Alliance (HCA) is a nonprofit organization whose purpose is to raise public awareness and build community support around the need to preserve the natural resources and heritage of the Central Texas Hill Country. HCA was formed in response to the escalating challenges brought to the Texas Hill Country by rapid development occurring in a sensitive eco-system. Concerned citizens began meeting in September of 2004 to share ideas about strengthening community activism and educating the public about regional planning, conservation development and a more responsible approach growth in the Hill Country.

    THE TEXAS CONFEDERATE HOME FOR MEN, 1884-1970 Amy Sue Kirchenbauer, B.A. Thesis Prepared for the Degree of MASTER OF ARTS UNIVERSITY OF NORTH TEXAS August 2011 APPROVED: Richard Lowe, Major Professor Richard McCaslin, Committee Member and Chair of the Department of History Harland Hagler, Committee Member James D. Meernik, Acting Dean of the Toulouse Graduate School Kirchenbauer, Amy Sue, The Texas Confederate Home for Men, 1884-1970. Master of Arts (History), August 2011, 116 pp., bibliography, 91 titles. Founded in 1886 by a local veteran’s organization, the Texas Confederate Home for Men served thousands of veterans throughout its tenure. State-run beginning in 1891, the facility became the center of controversy multiple times, with allegations of mistreatment of residents, misappropriation of funds, and unsanitary conditions in the home. Despite these problems, for several decades the home effectively provided large numbers of needy veterans with a place where they could live out their remaining years. The home was finally closed by the state in 1965, and the buildings were demolished in 1970. The facility’s success helped to inspire Texas to introduce a veteran pension system, and brought forth a new era in the state’s willingness to take care of veterans once their wars were over. Copyright 2011 by Amy Sue Kirchenbauer ii ACKNOWLEDGMENTS This work would not have been completed without the guidance of Dr. Richard Lowe. He urged me frequently to move beyond the limits of what I thought myself to be capable of, and I am a better historian for it. His dedication to helping me achieve my dreams and hours spent editing my efforts will always be appreciated.

  • Hill Country Is Located in Central Texas
    TABLE OF CONTENTS Regional Description ……………………………………………………1 Topography and Characteristics………………………………..2 Major Cities / Rainfall / Elevation……………………………….3 Common Vegetation……………………………………………..4 Rare Plants and Habitats……………………………………..…4 Common Wildlife ……………………………………………..….4 Rare Animals …………………………………………….……....4 Issues and Topics of Concern ……………………….…………..……5 Project WILD Activities …………………….……………….………….6 TPWD Resources …………………………………………….….…….6 REGIONAL DESCRIPTION The Texas Hill Country is located in Central Texas. A drive through the Hill Country will take the visitor across rolling hills, crisscrossed with many streams and rivers. The Edwards Plateau dominates a large portion of the Texas Hill Country and is honeycombed with thousands of caves. Several aquifers lie beneath the Texas Hill Country. The Edwards Aquifer is one of nine major state aquifers. It covers 4,350 square miles and eleven counties. It provides drinking and irrigation water as well as recreational opportunities for millions of people. San Antonio obtains its entire municipal water supply from the Edwards Aquifer and is one of the largest cities in the world to rely solely on a single ground-water source. Springs are created when the water in an aquifer naturally emerges at the surface. Central Texas was once a land of many springs. Statewide, it is estimated that Texas currently has nearly 1,900 known springs. The majority of these springs are located within the Texas Hill Country. Many of the streams that flow through the rocky, tree-shaded hills of Central Texas are fed by springs. These streams are home to many species of fish, amphibians, plants and insects, which depend on a steady flow of clean water for survival. Some of these species (salamanders in particular) are found only in these spring- fed environments.

A record February low for San Antonio of 4 degrees was set February 12, 1899. It was also a record February low for Austin of -1 on February 12, 1899. During this historic cold spell, extremely cold temperatures affected the entire state of Texas.
