Yellowstone Diary: May 14, 2012

We set off from Salt Lake City at around 08:30 on May 14.  A promising day with very clement weather.  We arrived at the west park entrance at around 13:30 after making a few supply stops at West Yellowstone, MT.  The west entrance to the park is just a couple of mile east of the town

It does not take very long to leave the hustle of West Yellowstone behind in favor of the beauty and serenity of the Madison Valley.  Here we found elk in abundance, and also bison, but no calves.

We made our way first eastward 14 miles to Madison Junction, and then northeast another 14 miles  along the Gibbon River to Norris.  From Norris the road heads directly northward for about 20 miles to Mammoth Hot Springs.  At approximately 15 miles along this route there is a rest area named Sheepeater Cliffs, and here we found the lone yellow-bellied marmot shown below.

The image above was recorded at around 14:40 MDT, using the Nikon D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at 400mm,  Exposure was f/5.6 and 1/2500s, ISO 800 – yeah, I was in a bit of a hurry to get the shot off before the critter ran off.

We continued north to Mammoth, and then veered eastward through the Blacktail Deer Plateau.  Elk, pronghorn, and bison were scattered along the Northeast Entrance Road.  At the Tower Junction we encountered a small group of bison (below).  These animals were pretty skittish, and as soon as they crossed the road they provided us with a rather entertaining display of their running abilities

The images above (one) and below (four) of bison were recorded at about 16:30 MDT using the D4 and the 200-400mm lens at 400mm.  Exposures were f/5.6 and 1/100s, ISO 800.

Near the Thunderer Trailhead in Soda Butte Canyon we encountered the Moose cow and calf (nearly grown) shown below (next four images).  These images were recorded at 17:10 MDT using the D4 and the 200-400mm lense at 400mm.  Exposure was f/5.6 and 1/500s, ISO 3200.

On the return trip westward we encountered several herd of bison – all of these groups contained sturdy calves as shown below.  The three images below were recorded along the Northeast Entrance Road at around 17:45 MDT using the Nikon D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at 400mm,  Exposure was f/8.0 and 1/1600s, ISO 1250.

On our way out of the Lamar Valley we stopped for a shot (below) of the valley looking south from the eastern edge of Lamar Canyon.  Image recorded at 18:00 MDT using the Nikon D800E and the Af-S NIKKOR 24-70mm f/2.8 at 45mm, Exposure was f/11.0 and 1/125s, ISO at 100.

The area below Junction Butte is a haven for many species, including bighorn sheep, bison, mule deer, coyotes, and as shown below, pronghorn.  The image below recorded at 18:30 MDT, using the D4 and the 200-400mm lens at 400mm.  Exposure was f/8.0 and 1/800s, ISO 1250.

Finally, at the end of the day, or at least the end of the light, we encountered this black bear along the short spur road that leads from the Northeast Entrance Road to Petrified Tree.  Images recorded at 19:30 MDT using the D4 and the 200-400mm lens at 400mm,  Exposure was f/5.6 and 1/1250s at ISO 3200.

Images in this entry were processed using Photoshop CS5 (extended) with capture and output sharpening conducted using Photokit Sharpener 2 and Nik Software Plugins (Viveza 2, Color Efex Pro 2).

How did the new Nikon bodies perform?  The D4 is a truly remarkable innovation – although the sensitivity is very similar to that of the D3s, the dynamic range has been dramatically improved – even in the harshest lighting conditions, details in shadow and highlight regions were recoverable in ways in which no previous camera system has been able to render.

The D800E saw limited use on this portion of our adventure – tune in later for a more extensive review of results for this exciting instrument.

Yellowstone Diary: May 16, 2010 – Madison River


Each year in Yellowstone National Park and immediate environs, bison execute a cyclical migration between the lower valleys in winter and the high valleys in spring.  Driving eastward from the west entrance from mid-to-late May along the Madison River, you become part of this journey because the Buffalo frequently travel along the same road.  The image above, of two bison cows and their calves (count legs) was recorded at 18:30 MDT on May 16, 2010, using the Nikon D3s and the AF-S VR Zoom-NIKKOR 200-400mm f/4G IF-ED lens at 240mm.  Exposure was f/8.0 and 1/500s, ISO 1600.  Handheld.  Small herds of migrating buffalo will walk on the road surface (Highway 20/191/287,  same highway with various designations)  for significant distances, e.g., up to 0.5 miles, which can block both lanes of traffic for 20 minutes or more.  These animals are the largest terrestrial creatures on the continent (bull bison can weigh over a ton), so it makes sense for them to take the the more efficient  route (road) whenever possible.

The migrating bison superficially appear quite peaceful, but minor confrontations often occur.  The two animals shown above had a disagreement over the ownership of a particularly lush section of graze.  The interloper, left, lost his resolve rather easily.  The image above was recorded at 19:00 MDT, using the D3s and the 200-400mm lens at 400mm.  Exposure was f/8 and /1000s (+0.33 EV), ISO 1600.

The bison cows are remarkably attentive towards the calves, and while cow and calf are never parted for long, the herd also appears to engage in community protective behavior.  The image above was recorded at abut 19:00 MDT using the D3s and the 200-400mm lens at 400mm.  Exposure was f/8 and 1/1000s, ISO 1600.

The calves are normally happy to quietly skittle along beside the herd, but occasionally, without any apparent motivation, they will burst into a fit of rambunctious energy and go tearing around and through the herd.  A calf that has taken up this antic will carry on as such for several minutes.  I suspect that the elder bison find this sort of stuff to be undignified, if not outright annoying, but for the human it is genuinely entertaining.  Image above recorded at 19:00 MDT with photographical parameters as described above.  Cropped.

Of course this entry would not be complete without a close-up cute baby animal photograph.  I hope the image below fits the bill.
