Yellowstone Diary: May 17, 2012

Yes, it has been a while since I’ve had the chance to catch up on things.  Rest assured that I have not been neglecting my photo interests, but we’ve been out in the field a bit this spring and summer, and I’ve just not had the time to sort out a post, well, until now.

The images of the resident Swan Lake Flat sow grizzly and her two cubs are shown above and below (five images).  Images recorded at 07:40 MDT on May 17, 2012 using the Nikon D4 and the AF-S NIKKOR 600mm f/4G ED VR with the AF-S Teleconverter TC-14E II (1000mm).  Exposure was f/6.7 and 1/800s, ISO 2500 (+0.67 EV, adjusted in ACR).

Although Yellow-Bellied Marmots are common in the park, many visitors never see them.  One reliable location for spotting these critters is along the Northeast Entrance road at the junction of Blacktail Plateau Drive.  There is an exposed basalt formation nearby that is a favorite environment of the YNP marmots.  Early morning is the most likely time to view marmots here.  The image below was recorded at 08:35 MDT using the D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at 400mm.  Exposure was f/5.6 and 1/800, ISO 400 (+0.67 EV, adjusted using ACR).

Pronghorn are common along the Northeast Entrance Road near the area that lies below Specimen Ridge, where the landscape flatten out along Slough Creek (following three images).  We have sometimes seen newborn animals along this section as well as small bands of adults.  Images recorded at 10:15 MDT, using the D4 and 200-400mm f/4G ED VR II at 400mm.  Exposure was f/5.6 and 1/1600, ISO 400 (+0.33 EV, adjusted using ACR).

 

One of the major attractions in the YNP during spring is the presence of newborn Bison calves.  The distinctive coloration and boisterous behavior of these youngsters is impossible to resist.  One could easily spend an entire day watching them.  The image below was recorded at 10:30 MDT at the same location that we shot the Pronghorns above, using the D4 and the 200-400mm f/4G ED VR II at 400mm.  Exposure was f/8.0 and 1/640, ISO 1000 (+0.33 EV, adjusted using ACR).

The coat of black bears display a remarkable range of hues, from jet to light cinnamon.  The lack of a shoulder hump is a clear indication that this is not Griz.  The image below was recorded along the Northeast Entrance Road at 10:55 MDT, using the D4 and the 200-400mm f/4G ED VR II at 400mm.  Exposure was f/8.0 and 1/800, ISO 1600 (+0.33 EV, adjusted using ACR).

We encountered a very bold coyote near the Mud Volcano area.  This coyote strutted about the parking area like it owned the place.  The image below was recorded at 13:25 MDT, using the D4 and the 200-400mm f/4G ED VR II at 400mm.  Exposure was f/8.0 and 1/3200, ISO 1600 (+0.33 EV, adjusted using ACR).

Near the end of the afternoon we revisited Swan Lake Flat, and found the sow Griz and her two cubs still on patrol.  Similar setup as in the AM session, but this time shooting the Nikon D800.  Exposures were at f/6.7 and 1/1250s, ISO 1600 (+0.67 EV).  Images from the D800 at ISO 1600 contain much more noise than do either the D3 or the D4, but is entirely manageable (I used Nik Dfine on these images).

Yellowstone Diary: May 16, 2012

We work hard at getting lucky.  Although Yellowstone is home to a grand abundance of wildlife, this is not a zoo.  Viewing the park’s animals takes knowledge of their behavior, both as species and individuals, perseverance, and luck, lots of luck.  The result, recorded here, is an example of  just how much can be seen in a single day when all elements of the effort are working in your favor.

We began the day with a plan to revisit the area between Mammoth Hot Springs and Norris.  Just south of the Grizzly Lake Trailhead we found the black bear that we had seen on the previous afternoon.  A bit further along the Grand Loop Road along the way we encountered a small group of bison near Obsidian Creek.

The images above and below were recorded at 07:40, using the Nikon D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at either 270mm (above) or 330mm (below).  Exposures were at f/8.0 and either 1/800s (above) or 1/1250s( below), with ISO at 1600.

From the Norris Junction we headed east to Canyon Village to shoot the Lower Falls of the Yellowstone River from Artist’s Point in the morning light.  The two images below were recorded 08:30 MDT using the Nikon D800E,  and either the AF-S NIKKOR 24-70mm f/2.8G ED at 82mm with and exposure of f/11.0 and 1/100s (+0.33EV), ISO 100 (top) or the AF-S NIKKOR 70-200mm f/2.8G ED VR II at 200mm.  Exposure were f/11.0 and 1/100s (+0.33EV), or f/8.0 and 1/320s (+0.67EV).  ISO in both cases was 100.

I’ve shot the falls many times in all kinds of light and atmospherical conditions.  Two elements are required for a memorable image – the direction and quality of the light are key of course, but of nearly equal importance is the sky region along the plateau at the top of the image.  It’s not bad here, there is at least a bit of color and texture, but not too spectacular either, and thus the relatively tight crop.

From Canyon we headed south through the Hayden Valley to Fishing Bridge – no animals along the route.  We then set out eastward towards the East Entrance, and found a small group of Bighorn Rams along the north side of the road where the East Entrance Road tracks along Middle Creek.  There were approximately six animals in this groups, foraging just 30-50 meters above the roadway.  They wouldn’t have given us the time of day…

The five images below were recorded using the D4 and AF-S 200-400 at various focal lengths.  Exposures were all at f/8.0 with shutter speeds clustered around 1/1600s, with ISO at 1600.

I also shot this same group of rams with the D800 and the 200-400mm (the original VR) at 400mm, with example images shown in the three shots below.  Exposures were at f/5.6 and 1/1600s, ISO 1600.  Although I hesitate to reveal it since it seems unlikely, but head-to-head at ISO 1600, the D800 has a clear IQ edge over the D4- the dynamic range of the D800 sensor is stellar.

We returned along our outbound route north though Canyon Village, and westward to Norris Junction, and back north to Mammoth.  We then turned west again to investigate the Blacktail Deer Plateau and the Lamar Vallay on the way to the northeast entrance of the park.  Along the way we found a very-well habituated Coyote at around 14:20 MDT.  The three images below were recorded using the D4 and the 200-400mm VR II at 400mm.  Exposures were at f/8.0 and 1/1600s, ISO 1600.

We continued on eastward and found the young moose from the previous day near the Icebox Canyon signpost – right out along the northern side of the road out in the open.  The image below was recorded at 15:42 MDT using the D4 and the 200-400mm VR II at 400mm.  Exposure was f/8.0 and 1/250s, ISO 1600.

 On our return back to Mammoth through the Lamar Valley, we encountered two rangers in the process of relocating the carcass of a bison calf from a spot about 50 meters from the road up over a bluff so it would be out of direct site of the highway.  We watched as the two rangers went up the hill – one ranger lead the way up the hill armed with a shotgun, and the other carried the carcass.  More on this rarely observed ranger activity in a future entry…  The image below was recorded at 16:30 MDT using the D4 and the 200-400 VR II.  Exposure was f/8.0 and 1/2500s, ISO 1600 – yeah the light was changing really fast at this time, thus the kooky exposure parameters.

Traveling further west along the Northeast Entrance Road we found a small group of pronghorns crossing the road near the base of Specimen Ridge.  I am uncertain about whether the roads in Yellowstone are de-iced with salt, but this would explain the curious behavior of the three animals in the second image below.  Images of the pronghorns were made at 16:50 MDT using the D4 and the 200-400 VR II at 220mm (top) and 400mm (bottom).  Exposures were at f/8.0 and 1/1250s, ISO 1600.

We continued westward to Mammoth Hot Spring, and then south with the idea to make one last visit to Norris that day.  Lounging bears in Swan Lake Flat caused us to change our plans…  Images of bear recorded at 17:50 MDT using the D4 and the 200-400mm VR II at 400mm.  Image of photographers made at 200mm.  Exposure were made at f/5.6 and 1/320s, ISO 1600.

Yellowstone Diary: May 15, 2012

We began the day with a drive westward through the Blacktail Deer Plateau.  There is a rock jumble near the junction of the Grand Loop Road and the Blacktail Deer Plateau Road, and in this area we often have seen yellow-bellied marmots.  The best chance for viewing this industrious animal is on brightly clear chilly mornings – they seem to favor basking in the sun from a vantage with readily accessible escape routes.  The images above and below were recorded at 08:00 MDT, using the Nikon D4 and the AF-S NIKKOR 200-400mm f/4G ED VR II at 400mm.  Exposures were at f/5.6 and 1/2500s, ISO 800.  Handheld (invariably, ’cause that is why you buy this lens!!!).  The light changes rapidly in the early morning and I was caught a bit off-guard – thus the silly shutter speed (1/500s would have been plenty fast enough).

We continued further on down the road, and past Tower Junction to the Northeast Entrance Road.  We made a low-probability pass along the access road to Slough Creek Camp.  Near the south end of the road we found a small group of pronghorns basking in the morning sun.  The image of a young female (Below) was recorded at 09:00 MDT using the D4 and the 200-400mm f/4.0 VR II at 400mm.  Exposure was f/5.6 and 1/2500, ISO 500.

Slough Creek Campground had not yet opened at the time of our visit, however it was clear that the mounted brigade was fully active.  Images of the horse barn located near the campground (three images below) were recorded at between 09:15 and 09:30 MDT, using the D800E and the AF-S NIKKOR 24-70mm f/2.8G ED lens lens at various focal lengths.

A uinta ground squirrel kept a cautious watch over us while we milled around near the Slough Creek trailhead.  The two images below were recorded at 09:30 MDT, using the D4 and the 200-400 lens at 400mm.  Exposures were f/5.6 and 1/600s, ISO 500.

We continued eastward through the Lamar Valley to the northeast entrance of the park without spotting a single animal – it’s like that some days…  From here we continued along the Beartooth Highway almost to the summit.  The image below of Index Peak was recorded at 11:07 MDT, using the D800E and the AF-S NIKKOR 70-200mm f/2.8G ED VR II lens at 140mm.  Exposure was f/8.0 and 1/320s (+0.33 EV), ISO 100.

The road was closed just a few yards beyond the point were I made this shot (looking north).  Image recorded at 11:40 MDT, using the D800E and the 24-70mm lens at 52mm.  Exposure was f/8.0 and 1/500s (+0.33EV), ISO 100.

A Google Earth image of the location at which the shot above was recorded is shown below – exact center of the image:

 

On our westward retreat we stopped at the Lily Lake Campground, where I recorded the image of Index Peak shown below.  Image recorded at 13:00 MDT, using the D800 and the 24-70mm lens at 38mm.  Exposure was f/11.0 and 1/125s (+0.33EV), ISO 100.

Then back through the Lamar Valley, and then through the Tower junction.  Just a short drive west from the junction at Elk Creek Meadows we found a sow black bear (below) and two second-year cubs.  From the road to the position of these bears is several hundred meters – the image below is a modest crop of the original image.  Image recorded at 15:00 using the using the D800E, the AF-S NIKKOR 600mm f/4G ED VR, and the AF-S Teleconverter TC-17E II, producing an effective FX focal length of 1000mm.  Exposure was f/6.7 (minimum value with the TC-17) and 1/1000s, ISO 500.

We then continued traveling westward all the way back to Mammoth Hot Springs – no animals.  We decided to drive south towards Norris.  Near the Grizzly Lake Trailhead we encountered the local resident shown in the following five images.  The top two images were recorded at 17:00 MDT, using the D800E, the 600mm f/4G ED VR, and the TC-17E II.  Exposures were f/6.7 and 1/1000s, ISO 1250.

The previous two images were recorded with Griz on the east side of the the Grand Loop Road.  Although the growing crowd was well-behaved, it became evident that Mr. Griz wanted nothing more than to cross the roadway – as anyone who has ever been present at the big show will attest, there are no (none, zero) gaps in the crowded mass of folks viewing the bear, and thus the bear crossing is a significant hazard for both bear and people.  Remarkably, the bear veered north along the road, then quickly west across the asphalt at the first opportunity.  The point at which the bear crossed was bounded on the west side by steep high ground, which forced Mr Griz along the inside track along the west side of the Grand Loop Road, within approx 10-30 ft (yeah, ft) of the assembled masses.  Discretion being the better part of valor, I jumped into the passenger side of the truck cab, picked up the D4 + 200-400mm, and commenced to reel-off images as Griz wandered by.  The next three images were recorded at f/5.6 and 1/1000s, ISO 1600.

This entry was mastered using an NEC model PA301W monitor calibrated to 140 candelas per meter-squared (cd/m^2).
