I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. "[1] ") are described as follows:
1. LKMEAZ_120720_56.JPG: Wildlife Overpasses: The location of these wildlife overpasses and associated fencing are the result of years of agency collaboration and research that helped identify where desert bighorn sheep are most likely to cross the roadway. Overpasses were recommended because desert bighorn sheep prefer to cross at ridgelines and remain above potential threats. These structures, completed in 2010, marked the first desert bighorn sheep overpasses in the United States. Desert Bighorn Sheep: The Black Mountains that surround you may appear inhospitable in both terrain and temperature (summer highs reach 120 degrees F). However, the largest contiguous herd of desert bighorn sheep in the United States lives here. Desert bighorn sheep from this area have been relocated to help restore historical populations throughout Arizona, Colorado, Utah, and Texas. The above maps show sheep movement data collected along US 93 between mile post 3 and mile post 14 during the highway planning process. Although some sheep did cross the roadway, others viewed it as a barrier. In an effort to enhance habitat connectivity for desert bighorn sheep and improve motorist safety, the data collected provided the necessary information regarding desert bighorn sheep highway crossings and the best locations for three wildlife overpasses at mile posts 3.3, 5.2, and 12.2. Herd Fragmentation: Multi-lane roadways create barriers that block animal movements and fragment habitat. The result can be limited access to resources, inbreeding, and the potential to quickly spread disease throughout the herd.
2. LKMEAZ_120720_65.JPG: Taming the Colorado: You are looking into Black Canyon and a narrow, river-like portion of Lake Mohave. To your left, about 59 miles downstream, is Davis Dam. To your right, 11 miles upstream, is Hoover Dam. The US Government built the dams to tame the periodic flooding of the Colorado River, provide irrigation during dry periods, and generate electricity. The dams essentially accomplished these goals. What effects, however, did they have on the environment? The deep and wider waters attracted different bird species and altered the vegetation at the edges of Lake Mohave and Lake Mead. The slowing of the river's flow made the water temperature more constant, reduced sediment buildup below the dams, and disrupted the spawning cycles and habitats of native fish species.
3. LKMEAZ_120720_71.JPG: Wilderness Forever: "The love of wilderness is... an expression of loyalty to the earth, the only home we shall ever know, the only paradise we ever need..." -- Edward Abbey, Desert Solitaire Looking for a challenge, a new place to explore, or a refuge from the everyday, fast-paced world? Take a hike or camping trip in one of the many Wilderness Areas with Lake Mead National Recreation Area. Nine areas in Nevada totaling 185,000 acres, were designated as Wilderness by the US Congress on November 6, 2002, as places "where the earth and its community of life are untrammeled by man." They provide primitive recreational experiences and opportunities to enjoy solitude in the natural world near the Las Vegas metropolitan area.
Wikipedia Description: Lake Mead National Recreation Area
From Wikipedia, the free encyclopedia

Lake Mead National Recreation Area is a U.S. National Recreation Area located in southeastern Nevada and northwestern Arizona. Operated by the National Park Service, Lake Mead NRA follows the Colorado River corridor from the westernmost boundary of Grand Canyon National Park to just north of the cities of Laughlin, Nevada and Bullhead City, Arizona. It includes all of the eponymous Lake Mead as well as the smaller Lake Mohave – reservoirs on the river created by Hoover Dam and Davis Dam, respectively – and the surrounding desert terrain and wilderness.

Formation of Lake Mead began in 1935, less than a year before Hoover Dam was completed. The area surrounding Lake Mead was established as the Boulder Dam Recreation Area in 1936. In 1964, the area was expanded to include Lake Mohave and its surrounding area and became the first National Recreation Area to be designated as such by the U.S. Congress.

Amenities

Lake Mead NRA features water recreation, including boating, swimming, and fishing, on both lakes as well as the stretches of river between the lakes. It also features hiking trails and views of the surrounding desert landscape. Three of the four desert ecosystems found in the United States — the Mojave Desert, the Great Basin Desert, and the Sonoran Desert — meet in Lake Mead NRA. Tours of Hoover Dam – administered by the U.S. Bureau of Reclamation – are also a major attraction within the recreation area.

About 200,000 acres (81,000 ha) of the recreation area are managed separately under the Grand Canyon-Parashant National Monument, established in 2000. Water covers about 186,000 acres (75,000 ha) of the recreation area.
Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.) I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
