Turner crossed the Great Scheidegg pass from Grindelwald to Meiringen, for which see folios 45, 46 of this sketchbook (D04702, D04703), then descended to the valley of Rosenlaui and the Reichanbach falls. Here, as identified by David Hill, he is looking back up the valley towards the Wellhorn at centre – with the mid-afternoon sun directly above – the Rosenlaui glacier and Barglistock to left and the Wetterhorn at right. As Finberg noted, the initial ‘F’ would indicate a commission from Walter Fawkes for a finished version of this subject. This was never carried out and conceivably the leaf was initialled in error, the intention being to reserve the subject on folio 41 (D04698) which is not marked in this way but was worked up for Fawkes.
