A Cinder Cone Lava Butte

There is a 500 feet tall Cinder Cone Lave Butte in central Oregon between the towns of Bend Oregon and Sunriver Oregon. Lava Butte is a 7,000-year-old cinder cone located on the flanks of Newberry Volcano. It is part of a system of small cinder cones is capped by a crater, normally extends about 60 feet deep beneath its south rim and 160 feet deep from the north side. Lava Butte only single eruption in 1977, started the fissure spewing hot cinders to form the cone. 
A river of hot basalt flowed from a small volcano cover the large area remains largely free of vegetation. The Cinder cones normally happen as vents on the sides of volcanoes, largely shield volcanoes, stratovolcanoes.  The Lava Butte get hardened and created a natural dam in a river, and when it finally eroded, Benham Falls. Lava Butte is a fascinating example of the damage that volcanoes can cause!
The magma spewed from Lava Butte was Scoria and other volcanic ashes, and also contained some Basalt. Lava Butte primitive history is not confirmed. The Native American observed the eruptions and then ascended the prominent new landmark. I.C. Russel was the first geologist to get there for research purpose in 1903. He speculated that Lave Butte erupted almost 150 years ago. The parking lot at Lava Butte is limited to 10 vehicles and passes are issued for 30 minutes only at first come first served basis.
You can see the rugged Cascade Mountains in the background and acres of green grass and trees. You may also see the infrequent patch of colorful wildflowers, some trees, bushes, no vegetation, and under the right conditions, bears a small resemblance to the surface of the moon. The temperatures on the lava flow trail are quite warm in July, so you need to dress accordingly and bring sufficient water and sunscreen. Further a restroom and water available at the visitor center, and a restroom with no water at the summit of Lava Butte.

Hiking Trails of Lava Butte

The calderas Lava Butte hiking up is a year-round option. A scenic rim trail around the top of Lava Butte is .35 miles long. Hiking around Lava Butte is one of the popular activities in Sunriver. The three main trails offer varying degrees of difficulty.
  • Molten Land
  • Whispering Pines Trail
  • Black Rock Trail

Lava River Cave

The Lava River Cave entrance is just 700 feet from US 97. This is very popular Lave River Cave has ample parking area and a kiosk where propane lanterns may be rented. This is a narrow cave, contains unstable ceiling rocks, and is closed to the public but the longer northwestern part is unobstructed and straightforward to follow.
Moreover, the descent is supported by steps and railings down 150 feet via a slope of fallen boulders to the floor. That remains flat and level all the way, apart from a few small downward steps. Also, long ridges along the walls mark different levels of the flowing lava, and the ceiling is lined with solidified droplets, where molten rock once dripped. Source: CP

Old Faithful – A Cone Shaped Geothermal Geyser

A cone geyser called Old Faithful located in Yellowstone National Park in Wyoming, United States. This was the first geyser to name in the park in 1870. Old Faithful is a very predictable geothermal geyser, as it erupted every 44 to 125 minutes. The members of the Washburn-Langford-Doane expedition discover this Old Faithful geyser in 1870. It spouted at regular intervals. The boiling water being thrown from 90 to 125 feet at discharge lasted 15 to 20 minutes. So, they give the name to Old Faithful.  
Earlier it was used as a laundry place. Garments placed thoroughly washed when it erupted. This geyser is the most popular of the nearly 500 geysers in Yellowstone National Park. Old Faithful normally erupting a column of steam and super hot water expanding steam bubbles push the water overhead through the fissures in the rock until they overflow from the geyser.
Old Faithful is an example of a cone geyser visible on Earth’s surface as mounds of porous deposits of siliceous sinter. The historic Old Faithful Inn (1903/04) is one of the country’s great national park lodges; Old Faithful Lodge (1918/28) and other vintage buildings are also in the vicinity.

When does Old Faithful Erupt?

So, far more than 1,000,000 eruptions have been recorded. The nearby Steamboat is tallest and larger than Old Faithful geyser. The old Faithful reliability can be attributed to the fact that is not connected to any other thermal features of Upper Geyser Basin. The average height of an eruption is 145 to 150 feet with intervals between 60 to 120 minutes. In the 1930s, the eruption takes place 66 minutes but gradually increasing the time to 90 minutes. The result of increasing in time could be due to earthquakes affecting subterranean water levels.
The Old Faithful mathematical eruption is much predictable in terms of its next eruption. The temperature measurement at depth is 118 °C is similar to measure in the 1940s. However, the steam temperature has been measured by more than 350°F. Scientists estimate 3,700 to 8,400 gallons of water expelled during an eruption. But it mainly depends on the duration of the eruption.
The Old Faithful inspired early developers to build special viewing areas, lodging, and concessions for visitors to watch eruptions. The natural geologic processes of Old Faith continue to provide enjoyment to visitors to see this natural system. The Visitor Education Center provides visitors to an opportunity to learn about the geology, hydrothermal properties, and scientific study of Old Faithful and other hydrothermal features in the park.

Hanging Lake Colorado

Almost 1,000 feet up the steep walls of Glenwood Canyon, a natural hides away a basin full of water the color of Paris green, waterfalls roaring near the brittle shoreline of travertine. The bottom of lake is fully visible through crystal clear waters. This majestic lake is unearthed by a gold hunting prospector.  Hanging Lake was a private homestead and family retreat until falling into the hands of Glenwood Springs in 1910.

This is well protected by the White River Forest Service; this is a popular stop for those willing to take a short but steep hike to see the trout-filled, glacially formed watery haven seemingly suspended from the side of the canyon. Just a few hundred yards behind Hanging Lake is yet another waterfall, Spouting Rock, which jets through holes in the canyon walls.

The discovery of the lake tells of a man searching for gold in the canyon. The man found a dead horse at the opening of a gulch. When he followed the gulch up through the steep hillside through the canyon he came around the backside of the lake. This is how he first saw the small bowl-like basin hanging onto the cliffs below. As the time goes, the area served as a homestead and a private family retreat until it was purchased by Glenwood Springs after the Taylor Bill was passed by Congress in 1910.

Following the acquisition it started its extensive history as a public tourist stop. In the 1940s there is hosted a resort and cafe until the construction of Interstate-70 commenced in 1968. Hence, in 1972, the trail and the lake were returned to the protection of the Forest Service as part of the White River National Forest. This has been a progressively popular tourist destination since.

In 2011, the lake was named a National Natural Landmark by Secretary of the Interior Ken Salazar. The brittle shoreline of Hanging Lake is composed of travertine, created by dissolved limestone from the Mississippian Period Leadville Formation is deposited on rocks and logs, creating travertine layers.

Hanging Lake is located on a fault line and was formed when roughly an acre and a half of the valley floor sheared off from the fault and dropped to what is now the shallow bed of the lake. The turquoise colors of the lake are produced by carbonate minerals that have dissolved in the water. You'll also have several benches to relax and soak in the sublime beauty of this 1.5-acre lake.

Hanging Lake is one of the most popular hiking destinations in Colorado approximately 3.2 miles round trip, and two hours of hiking time. Behind the lake, hikers will discover Spouting Rock, a much larger waterfall that flows from a set of holes in the limestone cliffs of Dead Horse Canyon. Hanging Lake receives over 131,000 visitors per year. Because of the high amount of traffic, Hanging Lake faces the threats of ecological disruption.

Thousands of visitors and their effects of wading and swimming by humans and dogs are having a significant impact on the strange ecosystem of the lake. No dogs are allowed on the trailhead or left behind in cars. No fishing or swimming is allowed at the lake. This precious natural wonder is one we all must work together to protect by respecting the rules. Source: CP

Ramona Falls, Oregon, United States


Ramona Falls is a horsetail type waterfall on the upper Sandy River on the west side of Mount Hood, Clackamas County, Oregon, United States. Ramona Falls is located in forest along the Pacific Crest Trail at an elevation of 3,560 feet. Ramona Fall is 120 feet tall cascading and splitting into ever smaller fingers of water broken up by the hexagonal columns of basalt at the base of the cliff.

Hiking at Ramona Falls

The hiking of Ramona Falls is most admirable destination for thrill seekers due to gradual elevation gain. The climax of wondrous of Ramona Falls is a popular family hike is no longer a walk in the park. The eternal bridge at the Sandy River was wiped out but after some years, Forest service has restored the log bridge now. The river is although easy to get across on the logs, but could be hard with pets or small children. There was a sad incident took place here. When a hiker was swept off the seasonal bridge and gets drowned in the rising waters after sudden storms.

So, you need to be sure to wear proper shoes, take necessary things in your bag pack. One important thing you should keep in your mind, if there is heavy rain, then stop yourself and do not attempt to cross the Sandy River as water speed is too furious and fast.  Furthermore, Ramona Falls became part of the Mt. Hood Wilderness in 2009, so consider this is a hike into the backcountry with all the attendant precautions. If you photograph lover, then this is very picturesque and mild hike. The elevation climb was gradual that it felt very easy.

Ramona Falls Trail

A beautiful 7.1 mile Ramona Fall trail is heavily trafficked offers a number of activity options. The best time to use this trail from April till October. You can also accompany with your dog on this trail but must be kept on leash. Many people finish the trail in 2.5 hours. But we would recommend extending your time span to 4 to 6 hours to enjoy the natural scenery along the way.

However, your trip would have been fun relatively easy hike! Be prepared to walk on a log to cross the river! So, it is super pretty and cool empty trail.  The majority of the trail is a sandy mix that’s not too hard on the feet.  Also, prefer to make return trip on the north leg. That is so wonderful due to lush green path of Ramona Creek and magnificent towering cliff before veering south to head back towards the trailhead. This is most famous place, so expect to see many people especially on Saturday and Sunday.

Kingsley Lake! A Circular Lake of Florida

Kingsley Lake is a circular lake, that pilots call it the Silver Dollar Lake. The lake is almost perfectly round as well as nearly precisely two miles across.  It is located six miles east of Starke, in North Central Florida. It is believed that Kingsley Lake is formed as a sinkhole. There is an 85-foot deep hole in the middle of the lake. The water of Kingsley Lake is clear and blue.

There are 5.5 miles around the shoreline, and two miles across in all directions covers almost 2,000 acres. This beautiful lake is popular for its clear waters and recreational sports like water skiing and fishing. In Florida, surface water temperatures can cross the upper 90s and even go over 100 degrees on some days.

When the water is that hot, a bass is that hot as well and its metabolism goes into overdrive, with calories it consumes not going into growth but just to breathe and stay alive. Mr. Simeon Strickland (Great Grandfather of Patty Gayle’s) was a first non-Indian settlement at Kingsley in 1859.

There are more than a few hundred docks on the north and west sides of the lake and Camp Blanding is on the East and South sides. According to some sources, it is the oldest and highest lake in Florida, located on the edge of the Trail Ridge formation.

The lake is a very stable lake with a sandy bottom. Its deepest part is about 90 feet. Kingsley Lake is a perched lake mainly fed by rainfall and Surficial aquifer seepage along the Lake bottom. Kingsley Lake borders the huge Camp Blanding National Guard Base and bombing range.

Kingsley Lake is one of the best bass fisheries that you have probably never heard. The campground on the lake is a large facility with concessions, cabins, picnic pavilions, camp store, fishing, an arcade, boat rental, docks, and over 100 RV sites. The Strickland Landing, next to the camp area, is a swim park with large slides, floats, and paddleboats for rent. Source: CP
