Warm colours denote high elevation, and cool tones indicate low elevations. Note the three potential hallux impressions in G2-28 which may be indicative of three rather than two track-makers, as is commonly inferred. The curved ‘banana-like’ form of G2-18 is typical of the whole track and suggests that the G3 track cut the heel of the earlier G2 track. The same is true of G2-27. The data was captured using a Konica-Minolta Vi-900 by the authors and processed in Polygon Editing Tool Version 2.4 (http://www.konicaminolta.com/instruments/index.html).
