The logo uses an iconic modern line drawing of a mountain range. This is the most recognisable sight during the trips as they're usually centred in famous mountainous regions.
I've incorporated a moiré pattern into the shaded areas of the mountains to create an illusion of undulation and texture to the image, often seen in these landscapes.
The logo type is a simple modern geometric typeface with a tweaked 'Q' to tie in the brands iconic mountain logo.
