What is in this image? Be very specific. Scientific, Engineering style! No emotions, no opinions, no metaphors. Just the facts, as detailed as possible.

The image depicts three human figures engaged in the activity of cross-country skiing on a sloped terrain. The figures are illustrated in varying stages of motion, suggesting dynamic skiing movement. Each figure is equipped with two elongated narrow skis attached to their boots and is using two ski poles for propulsion and balance. The skis appear to make contact with the snow-covered ground, indicated by fine lines and dot texturing, representing snow. All figures are adorned with skin-tight bodysuits, helmets, and goggles, typical attire for cold-weather sports to provide both insulation and protection.In terms of positioning, the leading figure is depicted in a forward-leaning posture with one leg extended forward, which indicates the motion of gliding on the skis. This figure''s arms are positioned asymmetrically, one arm forward and one back, aligning with standard cross-country skiing technique. The second and third figures are rendered with subtle variations in pose but broadly reflect a similar skiing stance.The background of the illustration features minimalist representations of coniferous trees, simplified with triangular shapes and lacking detailed texture, implying a wooded mountainous area common in ski regions. There is a large signpost at the top left, displaying three paw-like symbols, the significance of which is not directly indicated but could symbolize a trail name or rating.The overall depiction is in a line drawing style without color, employing only black outlines and internal detailing to define forms and convey depth, suggesting an illustrative purpose perhaps for coloring or educational use.
