Over the next few seasons, the team expanded their digs, recovering other anomalous structures from the earthen mounds, such as the Temple of the Jaguar and the Temple of the Warriors. In 1927 they discovered an older structure underneath this latter, which they called the "Temple of the Chacmool" after a further example found of this distinctive statuary. These structures had frescoes which again exhibited a non-Maya style, or at least a hybrid of Maya and non-Maya. They also worked on the reconstruction of "el Caracol", a unique circular building believed (and later confirmed) to be an observatory. A separate archaeological dig, this one under the Mexican government, had also commenced working the site; the two projects divided the areas to excavate, continuing side-by-side for several years, in a somewhat guarded but nonetheless cordial fashion.
