I can’t find a direct answer in all the articles that I read about it. Get rid of "They liked the scenery". "They wanted to find land" well... aren’t they on land? I heard they did go through mountains. There was also a thing that I read that there was gold buried somewhere close to the trail too. My best guess would be the second one "they were lost in the mountains", because of how the question was stated. You can wait for another person to reply to play it safe. That’s just my guess
