BRIDGEPORT, Calif. (AP) — Avalanche debris was spotted during a search for a missing Marine who failed to return from a backcountry skiing trip through the Sierra Nevada, California authorities said Sunday.First Lt. Matthew Kraft began trekking the rugged Sierra High Route on Feb. 23 and was scheduled to complete it Monday or Tuesday near Bridgeport, northeast of Yosemite National Park.The search on Sunday will primarily be air-based because "ground searching has proven to be too dangerous due to snow instability and avalanche concerns," the Inyo County Sheriff's office said in a statement. Much of the area was deemed impassable because of heavy snow and rock falls, the statement said.RELATED: Marine on ski trip to Sierras reported missingSearchers on Friday located a Jeep that Kraft parked at the start of his trip near Independence, about 130 miles (209 kilometers) south of Bridgeport, Inyo County Sheriff's spokeswoman Carma Roper said Saturday.Crews from local, state and federal agencies were searching a 400-square-mile (1,036-square-kilometer) area from Yosemite down to Sierra and Inyo National Forests and Kings Canyon National Park, Roper said.A series of winter storms has dumped record amounts of snow in the Sierra and led to avalanche warnings in the backcountry.Kraft is an infantry officer who received survival training in the field, military officials said. 1395

Bill Nye the Science Guy has returned to his roots of explaining scientific concepts, but on a different platform – TikTok.On Thursday, the former TV show host posted two videos on the platform, which is mostly used by younger people, to demonstrate why the public should wear masks to prevent the spread of the novel coronavirus.In his first video, Nye starts by explaining why people in the scientific community want you to wear face coverings when you’re out in public.“Face masks, like this one, prevent particles from my respiratory system from getting into the air and then into your respiratory system,” said Nye. “Blocking the movement of air is an old trick.”Nye then demonstrates how scarfs can block the movement of air to keep our necks warm, but they don’t block air enough to stop his breath from blowing out a candle.Afterwards, Nye brings out a homemade face mask with two layers of cloth and a pipe cleaner. Although the mask is simple, Nye says it “blocks the movement of air very effectively.” He tries to blow the candle out with the mask over his face, but he can’t.“If you’re wearing one of these, you’re protecting yourself and those around you,” said Nye. @billnye ##WearAMask ##LearnOnTikTok ##TikTokPartner? original sound - billnye In his second video, Nye brings out an N95 mask, which are used to block particles in the medical community and by those cutting their lawns. He tries to blow the candle out again and it’s even more effective than the cloth face mask.“So, the reason we want you to wear a mask is to protect you, sure, but the main reason we want you to wear a mask is to protect me, from you, and the particles from your respiratory system from getting into my respiratory system,” said Nye. “Everybody, this is a matter, literally, of life and death. And when I use the word literally, I mean literally.”“So, when you’re out in public, please where a mask,” Nye ends. @billnye ##WearAMask ##LearnOnTikTok ##TikTokPartner? original sound - billnye Nye isn’t the only one advocating for face coverings. The Centers for Disease Control and Prevention (CDC) and other public health officials are also asking Americans to wear masks in public to help slow the spread of COVID-19, which has killed more than 133,000 people in the U.S. and the cases are continuing to grow.A growing list of states are actually requiring residents to wear face coverings before leaving their homes. 2434

BROKEN ARROW, Okla. -  A Green Country, Oklahoma couple got the opportunity of a lifetime, a free wedding from perfect strangers planned in a day."It's all because of God that all of this has happened," said Willow Creek Mansion owner Cortney Gertner.The sun set outside the Broken Arrow mansion Wednesday evening, but the excitement inside was rising. "I didn't think we would find a bride and groom," said Poppy's Garden owner Meagan Ferren.This all started with her leftover flowers from a photo shoot a few days before."She was going to throw all of the flowers away and I was like, you can't just throw all of those beautiful flowers away," Gertner said."I was like, I know it's going to make me absolutely sick to my stomach," Ferren said.But Ferren had an idea."Then she was like, no we should find somebody that wants to get married in the next day or two and I said, seriously? And she was like, yea, you should post something about that."Gertner put the post on the mansion's Facebook page offering a free wedding in just two days."Whenever I went to my Facebook app It was the first thing I'd seen," said bride Karissa Alexander, who said she thought it was hilarious."I sent it to him as a joke.""She kind of sent it to me laughing, you know. So I sent it back, 'do it,'" said then, fiance Tyler Alexander.He was kidding, of course.But it was too late.Just 24 hours later, Karissa's bridal suite was buzzing."It was actually setup for September of last year and we postponed it for this year."Reflecting on a trying year that left her handcrafted wedding dress sitting in her mother's closet waiting indefinitely for the day Tyler could finally see it.The moment, was unforgettable."Everything that's happened has been, I just feel like it's a God thing," Ferren said.Everything coming together for the anniversary date that chose them.The day, planned in a day, is one they'll never forget.Karissa and Tyler said they're extremely grateful to every vendor and professional that dedicated their talents for free to their special day: Willow Creek Mansion (Venue), Poppy's Garden (Florist), Tracie Carlton Event Planning & Design (Officiant husband Matt), Katrina Wheeler Photography (photographer), Laurannae Baking Co. (Cakes) and Mr. Letney who gave a Unity Cross.  2316

BERKELEY, Calif. (AP) — For tens of thousands of children in California, the biggest monsters this Halloween are wildfires that have thrown trick-or-treating into disarray.Nancy Metzger-Carter and her family have been in a San Francisco hotel since Saturday when a blaze in Sonoma County wine country forced them to evacuate their home in the small community of Graton.Every day, her 11-year-old daughter and 7-year-old son worriedly asked how they would still have Halloween because they left their costumes behind."We were like, 'No matter what, you're gonna have a Halloween. We're gonna figure it out,'" Metzger-Carter said Wednesday.Her son, who was going to be a ninja, settled for a SWAT officer costume they found at Target. Her daughter and her 10-year-old friend, whose family also evacuated, went to the Love on Haight boutique in the city's famed Haight-Ashbury neighborhood to put together hippie costumes."The people were so sweet to them. They found pants that will fit them. They were helping to cut them," Metzger-Carter said.Many families who live in and around wine country north of San Francisco have no neighborhood to bring their kids to collect candy because they're coming home to destruction, are still under evacuation orders or facing lingering power outages meant to prevent electrical equipment from starting fires in windy weather.And kids on the other side of San Francisco Bay, southeast of the Sonoma County blaze, are seeing Halloween plans literally go up in smoke."Today at work, our lunch conversation was: 'What are you going to do for Halloween if the air is not good?" said Hillary Sardinas, a field biologist in the Bay Area city of Albany. "It's obviously not the biggest issue with the fires. You care about people being safe. But yeah, it's potentially a lot of disappointed kids."Some parents like Sardinas may throw a Halloween party instead. She and her husband would host their daughters' preschool classmates with candy, a pinata and a movie if trick-or-treating isn't an option.If the air quality is acceptable, the couple will take their children out, likely wearing masks and for a shorter amount of time close to home.Smoke and poor air quality became too much for Traci Moren, an acupuncturist who lives in Berkeley. She decided to take her sons, ages 9 and 4, out of school and stay with a friend in Santa Barbara.Last year, they left town around Thanksgiving because of a wildfire. This time, they left Wednesday to make it in time for trick-or-treating, which is a "much bigger deal" to her oldest son."He was pretty upset when I told him we might not be able to trick-or-treat. His best friend already left town," Moren said. "I just want to make sure there's a way to make it happen."Moren's older son goes to a school with an annual Halloween parade. Around 400 costumed students walk around the playground and then around the block, Washington Elementary Principal Katia Hazen said. It ends with a dance party on the playground.The school considered having the parade through the hallways and stairs because of smoke but decided to go ahead with the usual outdoor plans Thursday.The so-called Kincade Fire in Sonoma County has burned 120 square miles (310 square kilometers), destroyed more than 140 homes and forced more than 180,000 people to evacuate at its height. It's more than halfway contained, and most people have returned home. Despite widespread blackouts by the state's largest utility, electrical equipment that wasn't shut off may have ignited the flames last week.Strong winds also have whipped up wildfires in Southern California, destroying houses, forcing people to flee and leading utilities to cut power.In Sonoma, which was hit hard by the fire, the Boys & Girls Clubs of Sonoma Valley's main location will be open until 5 p.m. on Halloween, even to kids who aren't members. Clubhouse director Jonathan Antimo is expecting more than 100 children.The clubhouse will host a mini Halloween carnival with a costume contest, a doughnut-eating contest, "spooky tag" and movies. They also will let kids trick-or-treat room to room."We're going to try to keep the Halloween spirit alive and keep the kids happy and the fire out of their minds," Antimo said.Planning the festivities has kept his staff from feeling stuck at home and stressing about the wildfire."Our team is just really excited to help. They all jumped at the offer to come in and work," Antimo said.Parents can go to Airnow.gov to look up the air quality index by city, said Mary Prunicki, director of air pollution and health research at Stanford University's Sean N. Parker Center for Allergy and Asthma Research. If it's above the yellow level of "moderate," which is still considered acceptable, children should stay indoors."If you still want to trick-or-treat, perhaps alternatives such as trick-or-treating at an enclosed apartment complex or senior facility or mall should be considered," Prunicki said by email.Even children wearing masks shouldn't stay outside for too long, she added.Metzger-Carter said she's grateful her children will still have a Halloween, even if it's trick-or-treating away from home."We're so fortunate to be able to be at a hotel and to be able to purchase a costume," Metzger-Carter said. "Honestly, these disasters hit vulnerable populations so much more than people like us who can choose to stay at a hotel another night." 5416

BORREGO SPRINGS, Calif. (KGTV) - California State Parks are preparing for wildflower blooms across the state. The unpredictable and rare occurrences attract thousands of people to the parks. Some of the most beautiful blooms take place in desert landscapes. These rare blooms occur when precipitation levels in the areas are high, combined with years-long drought that eliminate grasses and weeds that take up nutrients. These conditions cause wildflowers to thrive. Vibrant wildflowers can already be seen sprouting from the typically barren brown soil in Anza-Borrego Desert State Park.“This area is just a mosaic of a painter’s colors," said Danny McCamish, Senior Environmental Scientist for the Colorado Desert District and Anza-Borrego State Park.RELATED: Photos: Gorgeous spring bloom carpets Anza Borrego desert"The early October, November rains started that germination process early this year, and so as the December, January, and February rains came in, all of the area was ripe to go off like this."Cooler temperatures are also a factor in prolonging the bloom, which the region has been experiencing thanks to snow in the mountains. McCamish says during the 2017 'super bloom' word of the beauty spread fast on social media, drawing in 6,000 to 7,000 cars a day.He says the rush of visitors overwhelmed the small town of Borrego Springs but that this year they're more prepared. Restaurants are planning to offer to-go meals and rangers will set up pop-up visitor centers to spread out where visitors go.McCamish recommends people check out other parts of the 700,000-acre region, including Ocotillo Wells State Vehicular Recreation Area.And if you plan to spend the night figure out lodging ahead of time, whether that be a hotel or camping.In addition to the flowers, visitors can enjoy nature on a bike. Bike Borrego offers tours on electric bikes, as well as bicycles for more advanced riders. California State Parks offers these rules and tips for visitors:Take only pictures, flower picking is prohibitedPick up all trashUnderstand the area; cell coverage may be spottyKnow your vehicle's limitsVisit the parks during the week and arrive early to beat the crowdsCheck weather conditions beforehandBring plenty of food and waterDrink plenty of water before your visit to remain hydrated and avoid heat-related emergencies 2348
