Watercolour. [title overwrites annotation to similar effect] "RF" top right corner FitzRoy

The left foreground contains a sloping contour running from the left-hand edge of the middle of the picture into the centre, coloured darkish purple. Behind this slope a rockier outline in paler purple is visible, behind which Mount Sarmiento itself rises abruptly and jaggedly to two peaks, coloured white, with grey shading indicating the shadowed surfaces to the right. The sun is shining from the left perpendicular to the line of sight. In the background the sky is painted faint purplish-blue, with some indication of cumulo-cirrus cloud from the top left-hand corner to the centre above the white peaks.
