Maritime names of Washington by Richard W. Blumenthal
Maritime Names of Washington is a wonderful companion if you are a boating enthusiast or simply curious about Washington’s maritime history. This book is a scholarly study on the origins of place names for our coastal and inland waters. It covers every name that appears on current nautical charts, from the Pacific Coast to the Strait of Juan de Fuca, the San Juans, and Puget Sound from Port Townsend to Olympia. It includes every named island, bay, point, inlet, pass, harbor, rock, channel, strait, canal, peninsula, sound, and shoal. The book also features many local and historical names that are not shown on the charts. The manuscript generally identifies the individual who named the place, when, why, and for whom. It also identifies the chart where the name first appeared and the early settlement history of many places. The manuscript is richly annotated and uses many quotes from the observations of our earliest explorers to give readers a glimpse of what Puget Sound country looked like 200+ years ago. Each of our early explorations is discussed in detail as they relate to individual place names. The book contains 170 pictures and 44 historical nautical charts from 1790 to 1900 that show many of the names

Chimacum In the valley near the water by Nancy L. McDaniel
"In the Valley, Near the Water" are the first words of Chimacum High School's Alma Mater song. Written by Duane Montgomery, cherished music director, those words have a special meaning for Chimacum residents.
Published in 2023 by local historian Nancy L. McDaniel, Chimacum: In the Valley Near the Water provides an intimate local history of the Chimacum Valley and its surrounding agricultural communities on Washington's Olympic Peninsula. The narrative chronicles the area's transition from ancestral indigenous homelands to a bustling hub of pioneer farming, timber harvesting, and dairy production driven by 19th-century homesteaders. Drawing on extensive family archives, oral histories, and photographs, the book meticulously reconstructs the daily lives, schoolhouses, and community networks of early settlers. A keen insight drawn from the text is how its granular, bottom-up preservation of rural genealogy reveals the quiet, persistent labor required to carve an agrarian society out of a heavily forested frontier, offering a localized counterweight to grand narratives of Pacific Northwest expansion.

Jann Castleberry’s revised fourth edition … is a fresh and expanded version of Cleland’s original. Historic photographs sourced from individuals, museums, and archives provide a valuable visual supplement to the original text. Castleberry also solicited new submissions from Quinault area residents whose stories compliment those captured so many years ago.”--Introduction

"A Sound Defense" is a comprehensive description of military sites of Puget Sound. Military historical sites in the twelve counties (Whatcom, Skagit, Snohomish, San Juan, Island, King, Pierce, Thurston, Mason, Kitsap, Clallam and Jefferson) are described with an emphasis on the unique things which happened there. Over 150 pictures and maps are included. Nancy McDaniel, Colonel, USAF, MSC (Retired) is a Washington State native and brings a love of the area and combines that with a perspective on the contributions that the military has had on Western Washington. "A Sound Defense" describes blockhouses built during the Indian conflicts. It addresses "The Pig War" and the politics of the international relationships which helped establish the boundaries of the United States. Forts built to protect Puget Sound as a result of the decisions of the Endicott Board are described along with the personalities of the commanders and personnel who were assigned there. Long forgotten installations established to provide early warning of approaching enemy aircraft are prominent in this comprehensive book. Lighthouses throughout the area are highlighted with the inclusion of historical photos and stories of early lightkeepers. Most importantly, "A Sound Defense" recognizes the contributions of military personnel throughout the years by the inclusion of memorials and facilities dedicated to recognizing their service to the country.
