Book excerpt: Garden photographer Janet Loughrey has covered the vast Adirondacks region to document how people have overcome the area's challenging mountain climate to create beautiful gardens for the past 150 years. Her profiles of contemporary gardeners and landscapers and their creations are supplemented with fascinating historic photos of the lavish landscaping of famed Adirondack-style estates such as Nirvana and the Knapp Estate and grand old hotel resorts such as Scaroon Manor and Sagamore.
