Crater Lake, located in southern Oregon, is a breathtaking natural wonder that has been the site of Crater Lake National Park since 1902. The lake is the deepest in the United States and the seventh deepest in the world, with a depth of 1,949 feet. It was formed over 7,700 years ago after the collapse of Mount Mazama and is filled with pristine blue water, the result of more than 150 inches of snow each year.

The park is home to many breathtaking geological features, including the Wizard Island cinder cone, the Phantom Ship rock formation, and breathtaking cliffs that plunge into the depths of the lake. Visitors to the park can explore the lake’s rim by hiking, camping, and picnicking. There are also boat tours that provide a unique perspective of the lake, as well as a lake cruise in the summer months.

The park is home to a variety of wildlife, including deer, elk, bears, and many species of birds. Visitors may also spot eagles, ospreys, and other raptors soaring above the lake. There are also a few types of non-venomous snakes at Crater Lake.

Crater Lake is a natural wonder that is not to be missed. Its beauty, serenity, and wildlife make it a unique and unforgettable experience. The park provides a stunning backdrop for spending time with family and friends and a chance to experience the beauty of nature.

No need to be alarmed. No poisonous snakes inhabit Crater Lake. Oregon is home to two kinds of Western rattlesnakes, which are the only venomous snakes in the state. The Northern Pacific subspecies can be found in the southwestern part of Oregon, the middle and southern Willamette Valley, and the Columbia Plateau. The Great Basin subspecies is located in south-central and southeastern Oregon.

Rubber Boa (Charina bottae) is a species of snake found in the western United States and Canada. It is one of two species in the genus Charina, the other being the Arboreal Rubber Boa (Charina Arborea).

The rubber boa gets its name from its skin, which is soft and wrinkled and covered in small, shiny scales. It can be tan to dark brown, olive green, orange, or even yellow. Newly born snakes are usually pink and slightly translucent, but this changes as they age. These snakes have small eyes with upright ellipse-shaped pupils and short heads that are the same width as their bodies. Additionally, they have short, unpointed tails that look just like their heads. Because of these features, these snakes are usually easy to spot among other species that inhabit the same area.

The rubber boa is a slow-moving snake that feeds on small mammals, lizards, amphibians, and occasionally small birds. It is a secretive species and is usually found hiding under rocks or logs. It is a nonvenomous species and is not considered a threat to humans.

The rubber boa is a popular pet due to its docile nature and small size. It is an ideal pet for those who want a snake that is easy to handle and requires minimal care. They are also popular among reptile enthusiasts who appreciate their unique appearance and behavior.

Eastern Racer, also known as Coluber constrictor, is a species of nonvenomous snake found throughout much of North America. It is one of the longest species of snake in the region, reaching lengths of over six feet. The average length is between two to five feet, which includes the tail.

Eastern racers are usually slender and smooth-scaled, with a grey to brownish-green coloration. Their underbelly is lighter in color, usually tan, yellow, or white. They are fast-moving and can be seen basking in the sun on roadsides, lawns, and other open areas. They are diurnal, meaning they are active during the day, and they feed on small animals such as frogs, lizards, and mice.

Eastern Racers are a beneficial species for humans, as they help keep populations of small animals under control. They are also valuable to the environment by helping to keep food chains in balance.

Despite their large size, Eastern Racers are nonvenomous and not considered a threat to humans. In fact, they often flee from people and can be quite skittish. If startled, they will usually coil up and hiss but will rarely bite.


The Western terrestrial garter snake (Thamnophis elegans) is a species of aquatic and terrestrial garter snake native to western North America. It is one of the most widespread garter snake species, found from southern British Columbia south through most of California and east to western Montana. It prefers wet areas and is a common snake to see around Crater Lake.

The snake is medium-sized, typically ranging from 20-40 inches in length. It is mostly gray or brown in color, with two yellow or white stripes running along its body. Its head is usually black, and it has a yellow or white collar around its neck. The belly is generally yellow or white, sometimes with black spots.

The western terrestrial garter snake can display a wide range of colors on its back and sides, including yellow, light orange, white, red, and black. Even though it is a fairly common species, accurately identifying it can be difficult due to its variety of patterns.

These snakes feed mainly on amphibians, fish, and small mammals. They are mostly active during the day and hibernate during the colder winter months. They are a non-venomous species and pose no threat to humans.


The Northwestern garter snake (Thamnophis ordinoides) is a species of snake that lives in the Pacific Northwest of North America. It is a medium-sized snake, typically growing to between 16 and 23 inches in length. Its body is typically brownish-green, with a yellow or white stripe running along its back. Although there are many variations of color, including a dorsal color of gray, black, brown, or dark brown. Their stripes can be orange, red, turquoise, blue, white, or yellow. These variations make them more difficult to identify.

This species lives in a variety of habitats, including grassland, shrubland, wetlands, and woodlands. It is a semi-aquatic species and is most commonly happy in the riparian areas of its range. It is a diurnal species, meaning it is active during the day.

These snakes are often seen basking in the sun during the day, as well as foraging for food. They feed on a variety of prey items, including insects, amphibians, and small fish. They are viviparous, meaning they give birth to live young.

Due to the Northwestern garter snake’s wide range and adaptability, it is not currently considered to be threatened. It is a beneficial species, as it controls insect populations, which can be damaging to crops. Despite this, they still face threats from habitat destruction, pollution, and predation.


The common garter snake (Thamnophis sirtalis) is a species of snake found across North America. They are usually between 18-26 inches in length and have a distinctive pattern of stripes on their back. They can grow to 54 inches in length if they live long enough. Their coloration is usually yellow, green, or brown, and they have black stripes and spots. The most common color variation is brown with yellow stripes, but many deviations exist.

Common garter snakes make their home in a variety of habitats, ranging from woodlands and fields to wetlands and near lakes and streams. They feed primarily on small fish, frogs, salamanders, and earthworms. They are diurnal creatures, meaning they are most active during the day.

Common garter snakes are non-venomous and usually shy away from humans when encountered. When threatened, they may coil up and strike, but they are not aggressive and rarely bite. They can also secrete a foul-smelling musk, which can be used to ward off predators.

Common garter snakes are an important species for many ecosystems as they help keep populations of their prey in check. They are also an important food source for other predators, such as birds of prey.

If you encounter a non-venomous snake at Crater Lake, there are a few things you should do. First, remain calm and do not panic. Snakes are a natural part of the environment and are usually more scared of you than you are of them. Secondly, keep your distance and give the snake space to move away. Finally, admire the snake from a distance and appreciate its beauty!

You can also take a picture or write down a description of the snake and report it to the National Park Service. They love to hear from visitors and keep an active log of which animals people spot.
