What are two details from the text that reveal that the man is a chechaquo, or a newcomer?

But all this—the distant trail, no sun in the sky, the great cold, and the strangeness of it all—had no effect on the man. It was not because he was long familiar with it. He was a newcomer in the land, and this was his first winter.

He remembered the advice of the old man on Sulphur Creek, and smiled. The man had been very serious when he said that no man should travel alone in that country after 50 below zero. Well, here he was; he had had the accident; he was alone; and he had saved himself. Those old men were rather womanish, he thought. All a man must do was to keep his head, and he was all right. Any man who was a man could travel alone. But it was surprising, the rapidity with which his face and nose were freezing. And he had not thought his fingers could lose their feeling in so short a time.
