Wikipedia Description: Black Canyon of the Gunnison National Park
From Wikipedia, the free encyclopedia

Black Canyon of the Gunnison National Park is a United States National Park located in western Colorado, and managed by the National Park Service. There are two entrances to the park; the more-developed south rim entrance is located 15 miles (24 km) east of Montrose, while the north rim entrance is located 11 miles (18 km) south of Crawford and is closed in the winter. The park contains 12 miles of the 48 mile long canyon of the Gunnison river. The national park itself contains the deepest and most dramatic section of the canyon, but the canyon continues upstream into the Curecanti National Recreation Area and downstream into the Gunnison Gorge National Conservation Area.

Geology:

The Gunnison River drops an average of 43 feet per mile (8 m/km) through the entire canyon, making it one of the steepest mountain descents in North America. In comparison, the Colorado River through the Grand Canyon drops an average of 7.5 feet per mile (1.4 m/km). The greatest descent of the Gunnison River occurs in the park at Chasm View dropping 240 feet per mile (45 m/km). The Black Canyon is so named on account of its steepness which makes it difficult for sunlight to penetrate very far down the canyon. As a result, the canyon walls are most often in shadow, causing the rocky walls to appear black. At its narrowest point the canyon is only 40 feet (12 meters) across at the river.

The extreme steepness and depth of the Black Canyon formed as the result of several geologic processes acting together. The Gunnison River is primarily responsible for carving the canyon, though several other geologic events had to occur in order to form the canyon as it is seen today.

Precambrian:

The Precambrian gneiss and schist that makes up the majority of the steep walls of the black canyon formed 1.7 billion years ago during a metamorphic period brought on by the collision of ancient volcanic island arc ...More...

1971 photos: From 1966 to 1975, our family lived in Franklin, Michigan while Dad worked for Kelly Services in Detroit. From 1954 to 1975, the bulk of these pictures were taken by my Dad, Glenn Guthrie At the time, he was using a complicated, but normal for the day, manual Kodak with light meters and such. All of Dad's pictures from this time were slides. From 1966 (when I started taking pictures) to 1979, I was using a Kodak Instamatic for most of my photos. From 1966 to 1989, all of my pictures were slides which is what I had grown up on. From 1966 to 1997, I was taking at most a couple of hundred photos a year. Image quality is going to be variable because these are scans of slides and/or prints. The images shown here were scanned in two phases. In the early years of the website, I rescanned a selection of pre-digital images, all at fairly low quality settings. During the COVID pandemic, I launched the Great Rescanning Effort, rescanning ALL of my pre-digital images from various media (prints, slides, negatives, etc) at higher resolution and quality settings. Mutilple versions of images -- some from the initial scannning phase, some from prints, some from slides/negatives -- were posted so there are frequently duplicate images on the same page. At some point, I hope to have time to do a final review and get rid of the duplicates but that'll have to wait until all of the pre-digital images are finally posted. Family trips this year: I rebelled against family trips -- my bedwetting was causing continual trauma for me -- and the family took my cousin Brian Bell with them to Colorado and Utah for the family trip.
