Where the Rocks Are Blue

We arrived at Glacier National Park late in the afternoon of the July 22, 2011.  After checking in to our hotel, we just couldn’t wait, and decided to take a quick run up the Going-to-the-Sun Road (GTSR).  It was by then after 20:00 MDT, and so we didn’t really anticipate having any notable photographical opportunities – but of course, you know what I’m going to tell you next.

Right, always be prepared for an opportunity.  Especially with wildlife that exhibit crepuscular behavior, you just have to be ready to make the shot should luck be with you.

We encountered this small band of Mountain Goats (Oreamnos americanus) at around 20:40, at a point where the roadway lies on top of locally-quarried stone blocks.  The exposed blocks provide the goats with relatively easy access to the rock surfaces, and specifically salts in the rock matrix.

Vegetation is uniformly low in electrolytes, and most vegetarian wildlife seek out supplemental salt.  Curiously, the amount of salt sought by goats (and virtually all animals) is much greater than their absolute dietary requirement.  The GTSR can be very crowded at times, but by early evening traffic is significantly reduced, providing the goats with a chance to fulfill their nutritional desires/needs in an easily accessed location.

Careful review of the image directly above (and the others to some extent) reveals that the tips of the goat’s horn are blue.  A remarkable feature of the stone in this area is that it is one or another shade of a distinctive dusty blue color.  I could not determine whether the goats seemed to favor one shade over another, but there is no doubt but that these animals were drawn to the place where the rocks are blue.

The goats didn’t seem to mind us much, and in fact a kid trotted right behind me on the way from one section of the wall to another – right down the middle of the road.

Images in this entry were recorded using the Nikon D3s (what else?!!!) and the AF-S NIKKOR 200-400mm f/4G ED VR II  (mostly at 400mm).  Exposures were at f/8.0 and 1/125s, ISO 3200.  Noise reduction was applied using Nik Software Dfine.  Further processing was accomplished using Nik Viveza 2 and Color Efex Pro 4, and Photoshop CS5.  Image sharpening was applied using Photokit Sharpener 2.

Bighorn Picnic

The most common question asked of rangers in Yellowstone National Park?  Number one would definitely have to be ‘Where can we see _______?  The most popular fill-in-the-blanks being bear and wolves in that order (or perhaps the reverse), with bighorn or moose vying for position three.

If the blank gets filled in with bighorn, then the answer invariably is ‘Yellowstone Picnic Area’.  Not only is this one of the most popular picnicking spots in Yellowstone, but it is also the most popular location from which to view bighorn sheep.  The site; which is properly known as the Yellowstone River Picnic Area, is located about 1.2 miles east of Tower Junction along the NE Entrance Road, and has nine tables and a restroom (separate M/W, pit type).

The location is the big seller here – as the name of the site indicates, it is located next to the Yellowstone River at a point where the river emerges from deep canyon walls in more open terrain.  One can walk south about 0.1 mile, ascending higher ground to a river overlook, or walk westward down-slope to gain river access after about 0.3 miles.  Alternatively, although not technically part of the picnic area, there is a parking area just above the river at a point approximately 0.3 miles west of the picnic area (or 0.9 miles east of the Tower Junction) that provides easy access.

Images in this entry were recorded on May 20, 2011, at 13:00 MDT, using the Nikon D3s and the AF-S NIKKOR 200-400mm f/4G ED VR II lens at various focal lengths.  Exposures were all at f/8.0, with shutter speeds in the 1/1000s range, and with ISO values near 1250.  I would generally make an effort to shoot big game animals using an aperature of f/5.6, e.g., to isolate the subject from the background.  However, as this group was moving around quite a bit, I was a little worried about the subjects passing out of focus before I could get the shot off and worked at f/8.0.  Also, the background in most of the shots shown here was sufficiently far off that I though it would be out of focus at f/8.0 anyway.

Capture, creative, and output sharpening was applied using Photokit Sharpener 2.  Images were converted using ACR 6.6.  Processing consisted of curves adjustments to the red and green channels to enhance contrast, followed by additional contrast, saturation and microcontrast (Structure) enhancement using Nik Viveza 2, and Tonal Contrast adjustment using Nik Color Efex Pro 4.

Note that the picnic area is located just a bit low of the center, where a couple of vehicles are visible.  The parking area is located a bit high of center, where there appears to be a single vehicle parked.

One Grizzly Specimen

Okay, so it’s a code…  Grizzly Bear obviously, but the specimen bit refers to the location at which we found this, well, specimen, of Ursus arctos horribilis.  Said location was indeed on the lower flanks of Specimen Ridge in Yellowstone National Park.  Griz can frequently be observed higher up on this massif, in or near the treeline, but rarely right along the Grand Loop Road, which is where we encountered this animal.  A land shark on patrol in a sea of sage.

BTW, this is too close.  The EXIF data recorded that the subject distance for the image above to be about 40 meters.  I seriously doubt the data, since as I recall, the distance seemed more like 40 feet…  Park regulations specify that ‘Approaching on foot within 100 yards (91 m) of bears or wolves or within 25 yards (23 m) of other wildlife is prohibited.’  Park regulations do not specifically address what happens when the wildlife approach you, but retreat whenever possible is naturally the best course of action. In this case, we were definitely retreating while the shooting continued.

Some folks believe that the taxonomic designation for Griz is unfair to the nature of the animal.  I dunno, but if you were standing as close as we were when this image was recorded, I’d bet you would agree that U. a. horribilis is pretty much on-target.  A most impressive creature, huge but remarkably agile, and definitely worthy of respect. As the bear strode past us, we had a rare opportunity to observe just how powerful this creature is.  I’d estimate that the strolling bear was moving a pace well above 5 mph, and that a person would have to jog at brisk pace just to stay ahead of the bear.  We’ve seen Griz move at full speed too, which is a bit better than 30 mph (for an average bear that is).  Compare that speed with that of the fastest humans, who move along at just over 20 mph, and you get an important suggestion – don’t get into a foot race with Mr Speedy.

Images in this entry were recorded at around 13:00 MDT on May 16, 2011 using the Nikon D3s and the AF-S NIIKOR 600mm f/4G ED VR lens.  Exposures were f/8.0 and either 1/1000s or 1/1250s, ISO 1600.  I’d have liked to use a larger aperture, but the bear was moving so swiftly towards us that I thought it best compromise in favor of just a bit more DOF.  Was 600mm necessary?  Yeah, absolutely no doubt.  I do get a lot of comments in the field… ‘Boy, I bet my pictures would be a whole lot better if I had *that* lens…’  Well maybe, and while I’m definitely privledged to be able to get my mits on the lens, I issue the fair warning that using big glass effectively is one helluva lot harder than it looks…
