Paperback. Etat : New. Print on Demand. This book presents an exhaustive statistical accounting of the forests in Colorado's Southern Front range, an area covering seven counties. The data was collected between 1982 to 1984 and reflects the state of forests owned by private individuals and the state during that period. The author provides a comprehensive breakdown of the composition of these forests, including their volume of timber, the rate at which the forests were growing, and the quantity of timber harvested each year, both for industrial and personal use. This information is presented as a series of easily digestible tables, making it a valuable reference work for foresters, landowners, community planners, and other stakeholders in the management and use of these important ecosystems. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item.…

Paperback. Etat : New. Print on Demand. This book, written by esteemed engineers William Griffith and Eli T. Conner, delves into the mining conditions beneath the populated landscape of Scranton, Pennsylvania. The study, commissioned by and in collaboration with the city council, school board, and various mining companies, assesses the risk to the city's inhabitants and infrastructure posed by the extensive coal mining operations below ground. The authors conducted thorough on-site investigations and historical research to understand the techniques and practices that have shaped the vast labyrinth of mine workings beneath the city. They have synthesized their findings and observations with meticulous detail and present clear conclusions about the potential threats to surface stability. The authors proceed to offer practical and innovative solutions to these problems, including engineered support systems for areas at greatest risk of collapse as well as long-term plans for mitigating the risks associated with future mining activities. This book provides an in-depth and authoritative account of the mining industry's impact on Scranton and serves as an essential reference for urban planners, engineers, and policymakers concerned with the safe and sustainable development of communities built upon undermined terrain.
