When you look at photos you’ve captured during a visit to a national park unit, do you notice one or more of your shots clearly showing a division of light and dark, or energy and calm, or two different colors, or two different textures? Contributing photographer Rebecca Latson sees this phenomenon in many of her own images, calling it the “yin and yang of a composition.” In this month's column, Rebecca provides examples of this yin-yang concept and how you can look for it in nature with your camera.

It’s no secret glaciers are retreating due to global warming trends. Different federal agencies have set up glacial monitoring programs to track these changes in the national parks. But don’t fret about a total disappearance of glaciers just yet. There are national parks in both the U.S. and Canada where you can still see, and even stand on, a glacier.

In a move intended to help wild populations of steelhead trout, fishing regs in Olympic National Park in Washington state are being tweaked.

Winter is one of photographer Rebecca Latson’s two favorite seasons of the year during which to visit a national park. There are fewer people, the vistas are much clearer due to fewer water molecules in the atmosphere, and the landscape looks so much different than it does during the warmer seasons of the year. So, this month’s photo column by Rebecca is about winter photography within the National Park System. Yes, she’s written about this before, but it’s always nice to have a little refresher course for those who regularly read the Traveler, and it’s a good introduction to winter imagery for those readers who are new to the Traveler.
