I highly reccommend this charming book produced by the folks at the National Forest Service non-profit museum in Montana, and chock full of recipes from forest ranger districts all over the country, celebrating 100 years of service. So it is filled with historic stories and photos of early ranger camps and cooks. Some of these vintage recipes have been around for awhile, and are very nostalgic. Most recipes list the contributing ranger, and their district. Spiral binding makes it easy to cook with, as you can keep the book open and flat on the page you need. All cookbooks should be made like that.
Most of these dishes are for cooking on a cabin stove or fire. The recipes rely on heavier fresh, dry, or canned ingredients similar to what you have at home. So any of these recipes can be made in your own kitchen, but are also good for RV and car camping. Starts with dutch oven cooking basics. Has chapters on breads, breakfasts, veggies, main dishes, and desert. Has an index. This book was released in 2004. It is 192 pages in length.
For a look at modern Ranger cooking see "Wilderness Ranger Cookbook", which is a modern ultra-light backpacking recipes cookbook from backcountry Forest Service Wilderness Rangers all across America. It is available at Amazon.
