Have you ever seen mud crack? A lot of rocks in Glacier National Park feature ancient mudcracks. This simple sedimentary structure is a clue to understanding what the area that is now Glacier National Park looked like in the past. At the end of the Precambrian, this area was covered in a vast, shallow body of water called the Belt Sea. Tidal flats located near the Belt Sea were intermittently covered in water. As the water receded, the mud would dry out and mudcracks would form. When is the last time you saw mudcracks? NPS Photo [A close up view of red rock with cracks running across the surface.]

331 million people visited National Parks last year (and even more in 2016) which is more than the population of all the United States! Are you one of the hundreds of millions who enjoyed their parks last year? What can you do to ensure the millions of visitors next year have the same great experience? Here’s one answer: #LeaveNoTrace! #LNT Image: Many people hike on the snow.

Don't Move a Mussel! Have your boat checked by a ranger before launching! Imagine a future where going to your favorite rock-skipping beach, you find the shoreline matted with tens of thousands of small mussel shells, with everything cemented together in a sharp, smelly mess. Imagine once productive fisheries wiped out by these new invaders. Since the 1980s freshwater zebra and quagga mussels have steadily advanced westward, transported on trailered boats. Very recently, a mussel-carrying boat was intercepted at a marina on Flathead Lake. The boat had come from the Southwest. Flathead Lake is just downstream from Glacier. All watercraft require a friendly NPS inspection and permit before launching in Glacier. Prior cleaning, draining, and drying of all watercraft, both externally and internally, will reduce inspection time significantly. #CleanDrainDry #AIS

Bull trout have lived in Glacier's lakes for thousands of years. They are a key predator in our aquatic ecosystem and an important part of the angling heritage of the area. . Currently, their numbers are threatened by lake trout that prey on them and out-compete them for resources. These non-native fish were introduced to Flathead Lake in the early 1900s and made their way into several west-side lakes in the park. In addition, bull trout require very cold water to survive, so warming temperatures are another concern. . In the case of many native species, including bull trout, they may face extinction if the park doesn't take action. Managers have made tough decisions to preserve the population, like gill netting to remove the lake trout and building barriers to prevent their spread.

What is a friendly way to remind someone to give the goats some space? πŸπŸ” Every year visitors get too close to wildlife in order to get a picture. Sadly, injuries have occurred as a result. Use a telephoto lens instead. This will not only ensure your safety, but the safety of the goats. Image: a series of images of mountain goats near people and traffic. Watch for wildlife. Stay at lest 25 yards from mountain goats. Use binoculars or a telephoto lens. Keep wildlife wild. #wildlifewednesday

During the Pleistocene Ice Age, Glacier National Park's valleys were filled with massive valley glaciers. The abrasive action of these glaciers carved the landscape below the ice, leaving behind massive U-shaped valleys. Have you ever seen a U-shaped valley on the side of a mountain? What happened? Just like how rivers have tributary streams, valley glaciers can have smaller tributary glaciers that feed into the main valley glacier. These smaller tributary glaciers may not carve as deeply as the main glacier they are feeding into. If that's the case, as the tributary glaciers recede, they can leave behind a U-shaped valley that appears to hang on the side of the mountain. This feature is called a hanging valley. This photo shows a beautiful hanging valley with clouds draped over the U-shaped terrain. This hanging valley was carved by a smaller tributary glacier that fed into a much bigger glacier that carved deeper into the valley below. Today Bird Woman Falls can be seen flowing out of the hanging valley. A great place to see this view is from the Bird Woman Falls Overlook located on the Going-to-the-Sun Road.

Do you think 2018 will be a big fire year? πŸ”₯ July 2017 was the driest July in Montana history and the 4th hottest July on record. That extreme hot and dry created the perfect conditions for wildfires in #GlacierNPS last summer. Whether or not 2018 will be a big fire year depends a lot on weather conditions this month. Regardless of the weather, Glacier will almost certainly see at least a few fires this summer. There has been a fire in Glacier National Park nearly every year of its existence. Though they can be scary, wildfires are a natural part of this ecosystem that many species depend on to survive.

Do you remember seeing or hearing about the Sprague Fire last year? Most of us recall the fire in terms of our own experience with the smoke, the flames, or the sadness of losing Sperry Chalet. But we don't always consider fire's effects on wildlife habitat. . Check out our story to join one of our wildlife biologists in the burned area, as she discusses fire's importance for different bird and mammal species.

The only fireworks allowed in Glacier are the explosions of color from the wildflowers! πŸ’₯πŸ’ Happy Fourth! πŸ‡ΊπŸ‡Έ Be careful with fires and remember that no fireworks are allowed in the park. Glacier is very busy this week so be patient and take time to smell the wildflowers like this Pacific Coralroot. #celebratesafely #wildflowerwednesday

How do you make your campfires?! πŸ”₯ The smell of woodsmoke and the pop and hiss of burning wood in a campfire brightens any night out in Glacier! However, you want to make sure you control your fire, and not the other way around! πŸ”₯ Never leave a campfire unattended. Always keep water nearby when you have a campfire. You might have a sudden need to put it out or the weather might change dramatically. Know what steps to take if someone is burned by sparks, hot cooking tools, or coals. Don’t forget to β€œstop, drop, and roll” if any of your clothes catch on fire. πŸ”₯ If your fire gets out of control, note your location and call 911 for assistance. If there is no cell service, contact the nearest park ranger or campground host to report the fire. πŸ”₯ Image: a campfire burns in a metal ring.

Who’s ready for the weather to warm up? 🌞 As you plan your 4th of July in Glacier prepare to encounter crowds, lines, and limited parking. Pack your patience, have a backup plan, and consider spending part of your holiday at one of our less crowded public land neighbors.
