I activated my ultrasound sensors and probably scared away all the birds and animals. Readings are really interesting: there is a temple at the end of this valley, which means that we are closer to Palenque then I initially thought. Cool...
The data I gathered back in the spaceship is really useful. Like I said, the portals are locked, but for every lock there is a key. The sacred item needed for activation of the portal in Teotihuacan is located somewhere in the Valley of the Jaguar. When we get close, I should be able to detect its magical presence. Then I'll be able to tell you what it looks like.
