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.

A google Earth image of the Yellowstone River Picnic Area appears below:

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.

Bighorn Sheep in Gardner Canyon

Ask any YNP Park Service employee about Bighorns.  ‘Go to Gardiner’, will be their response, or perhaps ‘Go to Gardner’, but it’s the same.  Regardless, that advice is not quite definitive.  They  may mean to refer to the city on the banks of the Yellowstone River, or they may mean the river that meets the Yellowstone just north of the park entrance, or they may mean the area between the confluence and Yankee Jim Canyon…

You are in fact most likely to find Bighorns in Gardner Canyon, although they appear semi-randomly, that is, unpredictably but always in weak light. In our experience, we find that the herds that wander close to the North Entrance Road below the McMinn Bench and Eagle Nest Rock consist mostly of mature ewes and young sheep of both sexes.

If you are so lucky as to be in the Canyon when the Bighorns are there, I suggest that you shoot them at f/5.6, since you’ll need the isolation.  These clever sheep…they are almost invisible in their native environment – the little teasers…  When they do emerge, ‘excess’ DOF is not a positive contribution, since it helps them hide, well, in the image that is…

Images in this entry were recorded at around 17:00 MDT using the Nikon D3s and the AF-S NIKKOR 200-400mm f/4G ED VR II.  Exposures were all at f/5.6 and around 1/640s, ISO 3200.  Yeah, that was ISO 3200.  If you are serious about stalking the Bighorns, bring your D3s, seriously.

Images were processed to reduce noise using Nik Dfine, then capture sharpening was applied using Photokit Sharpener 2.0.  The image was then processed to enhance contrast using Nik Viveza 2 and Nik Color Efex Pro 3.
