There is no shortage of mountains in Denali National Park. However, a layer of snow adds greatly to how they look. Snow especially contrasts against the darkest-colored mountains.
Bright white snow and very dark rock can potentially be an exposure challenge. When photographing landscape under full sunlight with snow in the frame, setting the ideal exposure usually involves bringing the image brightness level up to the point where the brightest snow has a tiny area of blinkies showing on the LCD (be sure that these are enabled). This insures that detail remains in the snow while shadow/dark areas have as much color information as possible.
You may have noticed that this image is not showing as full-dimensioned for the Canon EOS 5Ds R
used to capture it. This image was not cropped (the 100-400mm lens was not set to its longest available focal length), but as is often the problem with long distance photography, heat waves caused enough degradation that I opted to reduce the image size by 66%, using downsampling to improve image sharpness.
Note that I did not use a tripod for this capture. This lens' image stabilization system combined with a solid three-point sitting position (elbows on knees and forehead pressed into eye cup) were very adequate for sharpness in this regard, and a B+W HTC circular polarizer filter
blocking less light than a standard filter also contributed to this run-and-gun shot.
