  • These bison are a part of a free-ranging, currently publicly-owned herd of wild bison (commonly and incorrectly called buffalo) on Antelope Island, Utah that number upwards of 700 or more individuals. The habitat is perfect, as there are no wolves, bears or other apex predators, and the only limit to population is the amount of land that can support them.

  • One of the numerous species of catseyes found in the United States, the thicksepal catseye is a hardy and prickly native wildflower found in the arid regions of the American Southwest and is a great source of nectar for many of the insects . This one photographed in the Pawnee National Grasslands of Northeastern Colorado.

  • East Pawnee Butte in the Pawnee National Grasslands of Northern Colorado. This fantastic geological feature was only made more beautiful by the numbers of pronghorn antelope and desert wildflowers found dotted around the region.
    East Pawnee Butte
  • A band of pronghorn does look nervously toward a photographer on a mountain bike far out in the Pawnee National Grasslands on the plains of northeastern Colorado. Known to be the second fastest animal in the world (the cheetah is first), the pronghorn is the only surviving modern member of the mammal family (Antilocapridae) in North America. Evolved to outrun the now extinct American cheetah, the pronghorn has still retained its speed.
    Pronghorns!
  • This juvenile great horned owl would have gone completely unnoticed had it not been making the most horrendous racket in a tree in Sweetwater, Wyoming as I was photographing prairie dogs.

    American Bison on Antelope Island
  • Fossil records show that these bison have evolved and expanded across the north hemisphere in North America , Europe and Asia since the last ice age. In North America, several species of bison are thought to have thrived after the arrival of the first humans and the extinction of most of the ancient megafauna and other predators, such as the saber-toothed cat and dire wolf. The lack of competition for grazing across the vast prairies meant virtually no limit to population growth, considering the continent's vast size and recently extinct herds of other large herbivores.

  • Similar in appearance to many of the toxic hemlock species, Queen Anne's lace is a harmless member of the carrot famil that is native to Southwest Asia and some parts of Europe, but is now naturalized and found throughout most of North America. I found this delicate and beautiful one growing in Arkansas' Mammoth Spring State Park.
    Queen Anne's Lace
  • Found almost everywhere in North America from the tropics to the arctic circle, white clover is a naturalized, non-native member of the pea family deliberately brought to the New World as a high-protein food crop for grazing livestock. This one was part of a large patch growing in Northern Arkansas.
    White Clover
  • This invasive Eurasian species of the pea family is found across nearly all of North America, from Mexico to Northern Canada, from the Atlantic to the Pacific Oceans. This beautiful bloomer was found found growing in the Loess Hills region of Southwestern Iowa.
    Crown Vetch
  • There is some variety among individual populations of the glacier lily. In Wyoming, individuals have reddinsh/rusty brown anthers as seen here, and some populations I've seen elsewhere in the United States have pure white anthers, even though they are the same species.
    Glacier Lily
  • Glacier lilies are found in every western state in the continental United States except for Alaska, Arizona, and Nevada. They are also found in the Canadian provinces of British Columbia and Alberta. This one was photographed very literally on the Continental Divide in Wyoning's Yellowstone National Park.
    Glacier Lily
  • This beautiful, yet non-native ornamental invader is found in scattered populations across the United States and Canada. Unlike our native green mint and dead-nettle species, this native of Turkey, Iran, and Armenia has very attractive furry silvery leaves, which explains why it made its way to North America in the first place, as it was once popular in gardens with families with children. This one was photographed in Northern Arkansas.
    Lamb's Ear
  • Near the Montana/Wyoming border, I found a small herd of bison resting along the Madison River. This very young calf was fighting sleep, much the same as most babies do.
    American Buffalo Calf
  • A close-up of the  showy larkspur - seen here in Grand Teton National Park. Poisonous to cattle and somewhat dangerous to sheep - this summer bloomer is found at high elevation grasslands and meadows in western-central North America.
    Showy Larkspur
  • This non-native, naturalized beautiful member of the borage family can be near water throughout most of the states and provinces of North America. These blue forget-me-nots were photographed in Central Montana.
    True Forget-Me-Not
  • A common camas growing in a meadow in Northwestern Wyoming on a bright late-June morning. The bulbous roots are historically  a very important food source for several of the indigenous American peoples throught the western states, north of the deserts of the Southwest.
    Common Camas
  • The western serviceberry is a native member of the rose family that grows as a small compact shrub. If North America was divided diagonally NW/SE - this service berry would be common in the NW part - especially in Western Canada. This one was photographed<br />
 in its extreme southern range in Northwestern Wyoming.
    Western Serviceberry
  • This whole area was once an ancient shallow sea. These towering buttes of sandstone are all that remain after the surrounding rock and land were washed away by climate change. The rocks are still loaded with fossils of fish and seashells. Marine dinosaur skeletons have been found in region too!
    West Pawnee Butte
  • These fantastic cliffs are some of the only stand-out features in this remote part of northwestern Colorado.

  • A wild and free American buffalo (or bison) posed beautifully for me in the Grand Teton National Park in Northwestern Wyoming.
    American Buffalo
  • These Antelope Island bison have a distinct genetic heritage from all other bison in North America. They are potentially the most pure, in regards to the ancient populations that lived here up until Europeans first encountered them.

  • Native to Europe, this strikingly beautiful blue wildflower is now found growing wild all across North America and is a very important food for livestock, and as a coffee substitute or coffee-additive. Anyone familiar with some of the wonderful coffees from the New Orleans area will be very familiar with chicory coffee, which is very similar with a somewhat nutty taste, that is made from the roasted and ground roots. This one was found growing wild in at the edge of a field in Northern Arkansas.
    Chicory
  • A tachinid fly feeds on the flowers of Queen Anne's lace outside of Imboden, Arkansas. These specialized true flies have a very interesting reproductive behavior. The eggs (or newly hatched larvae - depending on the species) is laid on a very unlucky host (usually a caterpillar) where the larvae bores into the body. It will begin to eat its host alive, eventually killing it, and soon after emerge as an adult, ready to breed and repeat the cycle.

  • With its expansive range, this crown vetch is an invasive species with some benefit. The thick tangle of roots make this attractive Eurasian import with its odd-pinnate leaves very useful in preventing land erosion, and is often used as an ornamental ground cover. This particular one was photographed on the edge of a steep hillside in Iowa's Waubonsie State Park.
    Crown Vetch
  • American germander, also known as Canadian germander or wood sage, is a native member of the mint family. It is found growing wild in moist or wet habitats in every American continental state and every Canadian  province except for Newfoundland, Alberta and Alaska. Pollinated by long-tongued species of the bee family, it also attracts many types of butterflies and hummingbirds. This freshly blooming germander was photographed on the Arkansas/Missouri border next to a lake in early summer.

  • This glacier lily was part of a rather large, loose colony I stumbled into by accident in Yellowstone National Park in Wyoming. As I got out of the truck to take a picture of the roadside sign letting me know I was standing on the Continental Divide, patches of yellow stood out in bright contrast in the pines nearby. The sign let me know I was at exactly 7988 feet above sea level.

  • Found in nearly all of the western states and provinces of North America, the silvery lupine is very tolerant of many conditions and can be found in a suprising number of different habitats. This one was photographed at a rather high elevation in Wyoming's Yellowstone National Park.
    Silvery Lupine
  • A blooming sticky purple geranium opens its first blossom on a warm summer day in rural Montana at the edge of a mountain forest. This plant is a natural astringent, and has a long history of being used by Native American tribes for various medicinal uses.
    Sticky Purple Geranium
  • Lupine is one of North Americas most variable types of wildflowers, many species found in almost any kind of habitat that North America offers. These silvery lupines are blooming in Yellowstone National Park in Northwestern Wyoming. Very common in most of the western half of the continent in higher elevations, they are also very toxic to livestock.

  • Although beautiful with a vibrant blue to purple color, the showy larkspur contains toxins like several other species of Delphinium. This is one of many blooming larkspurs that were found around my campsite in Northwestern Wyoming as I was traveling across the continent.
    Showy Larkspur
  • Showy larkspur (also known as low larkspur) is a member of the buttercup family that is found growing in the Rocky Mountain states, the Dakotas, and most of Western Canada. This intensely purple-blue specimen was photographed a the edge of the Shoshone National Forest where it becomes Grand Teton National Park.

  • Close-up of the brittle prickly pear in flower just outside of Sterling, Colorado.
    Brittle Prickly Pear
  • The brittle prickly pear is likely the most widespread cactus in North America. It's range includes the five western Canadian provinces, all of the western American states, and continues south well into Mexico. Because it can be found close to the Arctic Circle, it is also the most northerly cactus in North America. This one was found in flower growing near the Pawnee Buttes in northeastern Colorado.
