The tone of the provided text is urgent, desperate, and serious. The use of phrases like "SOS," "I need help," "injured," "near death," and "too weak to hike out here" conveys a sense of emergency and immediate need for assistance. The mention of being alone and emphasizing that "this is no joke" underscores the gravity of the situation. The plea for help "in the name of god" adds a spiritual or desperate dimension to the message, intensifying the urgency.
Despite the urgency, there is a slight contrast introduced towards the end of the message with the mention of collecting berries and the intention to return in the evening. This adds a layer of confusion or ambiguity to the tone, as it seems contradictory to the initial plea for help and the dire circumstances described earlier. Overall, the primary tone remains one of urgent distress and a plea for assistance.
