The purpose of the LHZ project is to assist foresters and land managers in pre-identifying unstable slopes. The approaches for regulating forest practices on unstable slopes developed by the authors have several elements. It may include a report, maps and data sheets with varying titles from project-to-project depending on the WAU (watershed administrative unit). Per the agency, as of Dec. 2012 the project has ceased. Because of this, the elements for each WAU may vary and are complete at this time.

Feldspar minerals make up 60% of the crust of the Earth. They are stable in the upper mantle, and are so abundant in the crust that they form the basis of the classification of igneous rocks. At the surface, feldspars weather to form clay minerals which are the most important mineral constituent of soils. The articles in this book review the chemical reactions of feldspars over the whole sweep of pressure and temperature regimes in the outer Earth, and describe the fundamental aspects of crystal structure which underlie their properties. The book covers intracrystalline reactions, such as order-disorder transformations and exsolution, and transfer of stable and radiogenic isotopes, which can be interpreted to provide insights into the thermal history of rocks. It is suitable for final year undergraduates or research workers.
