Mountain Avens | The PhotoNaturalist

Though the main purpose of my trip was to photograph and video the birds of the tundra, I also got in a bit of landscape and flora photography. Lapland Rosebay (Rhododendron lapponicum) was by far the most dominant wildflower (actually a dwarf shrub) in the landscape. The showy purple-pink flowers dotted the tundra and edges of the boreal forests. At only a few inches high, it is funny to think of this as the same genus of the much larger Rhododendrons and Azaleas that are more familiar to us in “the south.”

I learned that the Canon EF 100-400mm f4.5-5.6L IS II USM lens makes a pretty darn good macro lens due to its amazing close focusing ability. You’ll see many “telephoto macro” images below using this lens.

I also used the iPhone 7+ for several landscape photos. Post processing them with Snapseed on the phone.

Oversized inch-long catkins dwarf the willow they belong to. I believe this is Salix arctica or Arctic Willow. [Churchill, Manitoba on Hudson Bay]

An interesting phenomenon I witnessed was the mirage of icebergs on Hudson Bay. Low floating pans of ice appeared to be giant walls of icebergs or a glacier when viewed through the heat shimmer of midday. [Churchill, Manitoba on Hudson Bay]

Willows, dwarfed Spruce, water pools and scoured bedrock dot the landscape along the shores of Hudson Bay. [Churchill, Manitoba on Hudson Bay]

Lapland Rosebay (Rhododendron lapponicum) is actually a dwarf rhododendron shrub that enlivens the tundra in early summer (mid June).

The dwarf rhododendron called Lapland Rosebay (Rhododendron lapponicum) is only a few inches tall (3 – 18 inches around Hudson Bay), but it has spectacular purple-pink blossoms. It is in the Family Ericaceae along with other small shrubs including blueberries, cranberries, Leatherleaf, Bog Rosemary, Bog Laurel and azaleas.

Lichen pattern

The white flower with red speckled petals is Saxifraga tricuspidata or Prickly Saxifrage (a.k.a Three-toothed Saxifrage), one of the most common Saxifrages in the Arctic. It is a colonizer of bedrock, taking hold in cracks. Its Inuktitut name is kakilahan.

Northern White Mountain Avens (Dryas integrifolia) ?? Not quite sure. The leaves below are not Dryas leaves, but maybe from another flower?

Interesting boulder with more resistant quartz veins.

The tundra is extremely colorful in the fall, but equally so in June in spots.

Northern White Mountain Avens (Dryas integrifolia) is a member of the rose family. It is a circumpolar species and is found across Arctic Canada into Alaska and west through Siberia. It is also found at high eleveations in the Rocky Mountains. This species exhibits “heliotropism” as the flower faces and tracks the sun as it moves across the landscape. This may be more attractive to insects as it creates a warmer microclimate. [Launch Road tundra; Churchill, Manitoba on Hudson Bay]

Northern White Mountain Avens (Dryas integrifolia) had gone to seed in the warmer parts of the Churchill area. Styles of the pistil elongate, twist and become fluffy heads from which the feathery seeds disperse in the wind. [Cook Street off Twin Lakes Road; Churchill, Manitoba on Hudson Bay]

Gulls, jaegers, terns, loons, sea ducks…All can be seen at the tip of Cape Merry (remnant ice chunks float in the background). [Churchill, Manitoba on Hudson Bay]

Speedboat in the Arctic? No, just a wonderfully shaped ice floe drifting past Cape Merry. It upended and sank a minute later. [Churchill, Manitoba on Hudson Bay]

Ice chunks on Hudson Bay and steel gray skies greeted me as I arrived in Churchill on June 16th.

Ice floated in and out of the shoreline areas of Hudson Bay during my entire visit (June 16-20). [Churchill, Manitoba on Hudson Bay]

“Flag Spruce” dot the tundra in clumps such as this. They are shaped by the harsh winter conditions; snowpack covers the lower branches, protecting them from the strong ground winds that carry ice chunks and scour the middle trunk of all its branches. The tip of the spruces still carry needle-bearing branches (the “flag”) as they are above the effects of the ice-scouring forces. [Launch Road, Churchill, Manitoba on Hudson Bay]

You may recognize the blueberry type pink flower of this ground hugging shrub. This is likely a species of Vaccinium but I’m not sure which.

Net-veined Willow (Salix reticulata) is a ground-hugging dwarf willow that span less than the diameter of a quarter on the tundra. [Churchill, Manitoba on Hudson Bay]
