Take a hike near Lovers' Lane

For those of you who love getting outside, you're in luck! Today is Take a Hike Day, an activity the American Hiking Society says will make you happier as you enjoy the great outdoors. And what better way to take a hike than a walk down Lovers' Lane in San Francisco's Presidio? The sinewy trail we see in today's photo is called 'Wood Line' and was designed by the environmental artist Andy Goldsworthy. By using felled eucalyptus trees, Goldsworthy intended this land art to eventually biodegrade and fade back into the forest floor. It's one of four of his works within this national park that once served as a US military outpost.

No matter where you are, we hope you'll find the closest trail to explore. The US National Trail System maintains more than 55,000 miles of National Scenic, Historic, or Recreational trails through some of the most beautiful, interesting parts of the country, so you have plenty of hikes to choose from.

Rocks on the move

No, that stone in today's homepage image didn't get there by itself. Or, did it? Not only is Death Valley one of the hottest places on Earth, it also boasts a mysterious geologic phenomenon—rocks that drift across the exceptionally flat desert floor, seemingly under their own power. The rocks here at Death Valley's Racetrack Playa are known as 'sailing stones' and they can vary in size from a few ounces to hundreds of pounds. As seen in our image, the stones leave long trails behind them as they move across the scenic dry lakebed.

Since the stone trails were first observed in the early 1900s, no one knew just how the stones managed to have apparently 'sailed' across Racetrack Playa without someone to push them along. Because they'd never been seen moving, the sailing stones gave rise to many wild theories to explain their mobility. Then, in 2014, scientists captured the movement of the stones for the first time using time-lapse photography, and the mystery was finally solved: The stones move only with the perfect balance of melting ice, water, and wind. One day that winter of 2014, rain had formed a shallow pond that froze overnight. When it thawed in the next day's sun, the very thin ice sheet melted and cracked into floating panels. Driven by a light wind, these sheets accumulated behind the stones, and very slowly pushed them forward.

A peek at an explosive peak

We're looking at Lassen Peak, a volcano also known as Mount Lassen, and its reflection in Manzanita Lake. This stunning scene can be found in northern California's Lassen Volcanic National Park, which was established on this day in 1916. The volcano erupted between 1914 and 1917 (with some activity as late as 1921), but these days the surrounding area is a calm destination of trails, lakes, and stark lava beds. One of the least visited parks, Lassen was the first national park in California to fully reopen after being closed for COVID-19, although it implemented some restrictions to park services and facilities. The park also includes acres of mud pots, hot springs, steam vents, and fumaroles to remind you of the heat that's below you, including Boiling Springs Lake—one of the largest boiling lakes in the world at over 500 feet wide.

National Parks Week begins

To kick off National Park Week, which starts today, we're turning our lens on Vernal Fall in California's Yosemite National Park. This time of year, the waterfall flows in a torrent, but by late summer it can be reduced to a trickle of small streams slipping over the edge. Most years, Vernal Fall is at full power by May, as the spring thaw in the mountains melts the snowpack, turning the falls into a raging tumble of water spilling to the valley floor where the Merced River flows.

Gray days ahead in Monterey

Grey whale migration is a rare scenery, thousands of gray whales, many with calves in tow, swim by this part of the Pacific coast as they migrate from the warm waters of Baja California to their summer feeding grounds in the Bering Sea. Come winter, they pass by again on the swim south. The entire roundtrip route clocks in at about 12,000 miles, making gray whales among the longest migrators of animal kingdom. Because they travel close to the coastline, it's also one of the few whale migrations you can see from shore.

Heron lies the Salton Sea

Migratory bird species are predictable frequent fliers, taking to the sky to travel along roughly the same route, at the same time, every year. Following sources of food and water along the way, the birds often fly great distances to reach breeding grounds or places to spend the winter. Today, we're looking at an important stopover for migratory birds—California's largest lake, the Salton Sea.

This shallow saline lake was formed when a dam broke in 1905, causing the Colorado River to flow into a 35-mile-long basin with extensive salt deposits. Now it attracts hundreds of species of birds in what is considered one of the most significant concentrations of bird life in the continental United States. Most of these birds are just passing through, migrating along the north-south route called the Pacific Flyway. They gather here, sometimes in the millions, to feed and regain strength before moving on. Some birds, like the heron pictured in today's photo, may stay here for the season, but most of those who visit in the spring will stay for just a few days before continuing their journey to a summer spot farther north.

Hollywood's big night

It's Oscars night in Tinseltown, and we're offering you a moment's escape from the paparazzi to gaze over the glittering megalopolis of Los Angeles—and to get an unfamiliar view of a familiar landmark. The Hollywood Sign originally read 'Hollywoodland' when it was erected in 1923 and festooned with light bulbs to advertise a real estate development. But within a few years, as the silent-film era gave way to 'talkies,' the sign evolved into a popular tourist attraction. Falling into disrepair in ensuing decades—at the peak of its decay, the sign was missing its third 'O' altogether—the original was demolished and a sturdier version built in 1978.

Though it's inspired similar designs advertising locales from Ireland to Taiwan to the fictional Simpsons' hometown of Springfield, the now-permanent Hollywood Sign is cherished by residents as uniquely LA. Today, a dedicated nonprofit maintains and promotes the sign as both a source of Angeleno pride and an emblem of romanticized Hollywood.

A seabird gets 'schooled'

This deep-diving Brandt's cormorant appears to be on the hunt for a meal, and there's plenty of Pacific mackerel to choose from here off the coast of Los Angeles, California. While seabirds like the cormorant are a threat to these fish, the mackerel aren't exactly defenseless. Fish have many unique means of defense, such as traveling in dense schools like this one. It's a technique that not only allows for speedy travel (because it reduces friction on most of the fish in the school)—schooling also makes it more difficult for predators to pick out an individual victim. For these fish, there's safety in numbers. But when all else fails, they can take some advice from Dory in 'Finding Nemo'—'Just keep swimming, just keep swimming.'

Welcome to California

These are the peaks of Mount Diablo, part of the Diablo mountain range in the eastern part of the San Francisco Bay Area. On a clear day, you can see all the way to the Sierras from here. In fact, this is one of the best viewsheds in the Bay Area, which is a feat, since the peaks are comparatively low for the region. While Mount Diablo may tempt you to take in the scenery or hike in the surrounding state park, the area offers compelling stories from American history as well.

November 4, 1841, marks the day when a group of about 70 people, led by 22-year-old John Bidwell, finally reached the West Coast after setting out from Missouri. This was the first time a wagon train used part of the newly established California Trail to emigrate to California. The trip was grueling, covering more than 2,000 miles. The wagons traveled at a pace of just 15 miles per day, pulled by oxen, horses, or mules. The journey required traversing part of the Oregon Trail and crossing such daunting obstacles as the desert areas around the Great Salt Lake and the steep slopes of the Sierra Nevada mountains. After five months, the wagon train arrived at the ranch of John Marsh near Mount Diablo. The successful journey helped pave the way for expansion to the American West and marked the route for future wagon trains during the California Gold Rush.

The height of pumpkin season

If you happen to be in the Bay Area this weekend, you might want to swing by the Half Moon Bay Art & Pumpkin Festival. The annual event displays enormous champion pumpkins weighing over a thousand pounds, hosts live pumpkin carving demonstrations, and offers really every kind of pumpkin-related food you can imagine, from pies to pumpkin flavored artisanal cocktails. Plus, Gourdy, the anthropomorphized pumpkin mascot. While California is the leader in the consumer pumpkin harvest, it is only the second-largest producer in the country. Illinois grows approximately a quarter of the 2 billion pounds of pumpkins the US produces yearly, though 80 percent of that ends up as pie filling or other processed products. Pumpkins require between 90-120 days to mature, so most are planted by late May or early June to coincide with our Halloween carving needs.

While carving vegetables into faces is a tradition in many parts of the world, the carving of jack-o’-lanterns around Halloween originated in Ireland in the mid-19th century, using potatoes or turnips. Irish immigrants brought the tradition to the US around the same time and discovered that the native pumpkins were much easier to carve.
