The Abandoned Excavation Site

As a highly motivated team of archaeologists, you have traveled to the northeast of India, to Arunachal Pradesh, to conduct research where no one had dared before you. Actually, you were quite successful with your project, but suddenly more or less unexpected circumstances befell you. The monsoon darkened the sky and washed away the only road that had so far enabled you to reach the surrounding villages. As your supplies became scarce and hunger grew, you saw your end, lost in the jungle, coming closer and closer, until suddenly you received a faint radio signal. Someone is looking for you! You look up - a rescue plane is circling above you. But the battery of your radio is almost exhausted. You have 60 minutes to make yourself noticed before the radio signal finally breaks off.
