Some optical weather phenomena are caused by airborne ice crystals that act like tiny prisms and diffract or bend the light slightly as the light passes through the ice crystals. Sundogs, also known as parhelia or mock suns, can be seen on opposite sides of the 22 degree sun halo just below where the mountain tops meet the sun halo. At the top of the 22 degree sun halo is a faint tangent arc. Also emanating from the sun is a very faint sun pillar (column of light) rising vertically towards the tangent arc but mostly obscured by the ice fog that is prevalent in much of the image. Even with temperatures hovering between -30 and -40 degrees Celsius, much beauty can be photographed in nature if you are comfortable and warmly dressed. Athabasca Glacier on The Icefields Parkway.

It is no wonder I could not identify the type of cloud shown above that I made a few years ago until just recently. That's because the World Meteorological Organization (WMO) only lately classified it as Asperitas, 1 of 11 new cloud types the WMO added in March of 2017 to their International Cloud Atlas. This is the first update that the Atlas has received in 30 years.
Asperitas (formerly known as Undulatus asperatus) was first observed back in 2006 by a member of the amateur cloud-spotting group in Cedar Creeks, Iowa who sent a photograph of the unusual cloud to Gavin Pretor-Pinney, president of the Cloud Appreciation Society in London, England. After receiving more similar photos, the new cloud type was proposed but only recognized 9 years later this past spring on World Meteorological Day.
I first witnessed these dark, storm-like clouds as I drove into Sault Ste Marie, Ontario around dinner time on May 25, 2008. I was immediately taken aback by the unusual, somewhat apocalyptic formation that appeared like rippling waves. The Asperitas clouds covered the entire sky (360 degrees!) and I had never in my life seen anything like that before. I expected a severe storm to materialize as we were adjacent Lake Superior but nothing happened. In fact, the distinctive, but relatively rare cloud formation almost always dissipates without a storm forming.
As is typically the case, I tend to process most of my RAW images only a few years after I make them, sometimes not until years later! In this instance, it took me more than 2 years to process this image after coming across this series of images I made while working on my Ontario book, which was published in the spring of 2015. The caption which accompanied the image on page 128 read: 'Menacing storm clouds, Sault Ste Marie'. Now, I would write: 'Menacing Asperitas clouds, Sault Ste Marie'.
The League of Landscape Photographers
‘The League of Landscape Photographers’ is a self-identified group of artists who photograph the natural world around them in accordance with high ethical standards. Essentially, it’s a movement of artists who create with a conscience. As the assault on our environment continues with garbage dumping, desecration of the land by graffiti, over-trampling and general disregard for the environment, its time has come.
As a naturalist, photographer and educator for more than 40 years, I strived to live life by a code of ethics that has governed my activities during my travels and at home. I respect the environment I explore by learning about it and not causing any undue stress upon either the environment or its inhabitants, the wildlife or the plants. I also respect private property.
I encourage others, whether photographers or the general public, to live life by a Code of Ethics. Respect is due not only to the environment or its inhabitants but also to the people who visit these areas and I afford them the same respect I would like them to bestow upon me.

I returned to Sandilands Provincial Forest this week with colleagues Dave Benson and Chris Gray to check out the progress of the prairie crocuses that Dave and I found last week. It was heartwarming to discover that spring had finally sprung! I made a number of images of Manitoba’s provincial flower growing in various micro-habitats. This particular image was made along a gravel road using the road as the background. Three images were made with a 200mm micro Nikkor lens set at an aperture of f/8 and focused at different points. The images were later stacked into Helicon Focus software to produce one image with as much depth of field as possible without incorporating any distracting background elements. To add to the challenge, mother nature began to blow and gust as we enjoyed the cool, evening weather. But it was just ‘grand’ to experience the great outdoors!
The prairie crocus, our symbol of spring on the Canadian prairies, is one of those wildflowers that I can never get enough of! I photographed these early blooms in Sandliands Provincial Forest on a cold morning using a 200mm macro lens. I made 7 different images focused at slightly different areas on the flower to gain a little extra sharpness on the closest bloom.Shooting at a wide aperture allowed the background to remain blurred and soft. I later processed the images in Adobe Camera Raw and then brought them into Helicion Focus, software that combines any number of differently focused images into one final image. The green color in the background is the result of fruiticose lichens growing amongst the crocuses at the edge of this particular jackpine forest.
