Argentina

"If your intention...the means are endless." (pg. 37)

I think this passage represents the tone aspect of voice, because it represents how Ernesto expresses his attitude. I think the reader can draw an inference, that Che does not care as much about the means as he does the ends. He mostly cares about his destination point, not the check points along the way.

"I lost and plunged in....we saw abysses every second moment." (pg. 48-49)

I think this passage represents the imagery aspect of voice, because it brings about many of the senses, on this particular point in the journey. It talks about the feel of things (cold air, rocks), the sight (view, moon, in darkness) and sound (strange noises). So it incorporates many of the senses in this point of the journey, which is essentially the imagery aspect of voice.
