A mountain pass in the Swiss Alps stands out in sharp relief against a brilliant blue sky. The picturesque landscape is a masterful study of the clear alpine light and air on the rocky terrain. Sargent applied the varied brushwork he used in his portraits to this landscape — compare the rushing stream at left, to the light, sketchy vegetation, to the hatch-like strokes on the rocks in the foreground. The darker, dryly brushed middle ground sets off the majestic peak. Thin, hazy clouds and pockets of snow connect its long slope to the brilliant sky above.
