El Yunque National Rain Forest is located in Luquillo, Puerto Rico. It is the largest subtropical rainforest in the US National Forest System and contains a high level of biodiversity. The group gathered data on environmental factors like temperature, humidity, and pH at different areas of El Yunque during their visit. They found that temperatures decreased deeper into the forest. The pH ranged from 6 to 7 and humidity varied between 0-2. El Yunque is an important ecological resource for Puerto Rico that protects many endangered species and ecosystems.

2. The resemblance in form has Yunque Peak to
the part used by the blacksmith to do their jobs.
5. Purpose of this trip:

6. History
In 1876 the Spanish crown declared "Area
Montes" the highest part of the Sierra de
Luquillo.
At that time it had 12,399 acres of extension.
For this reason it is understood that the
