The Chavín culture had a wide sphere of influence throughout surrounding civilizations, especially because of their location at a trade crossing point between the deserts and Amazon jungle. For example, Pacopampa, located north (about a 3-week trek) of Chavín de Huantar, has renovations on the main temple that are characteristic of Chavín culture. Caballo Muerto, a coastal site in the Moche Valley region, has an adobe structure created during renovation of the main temple, the adobe related to Chavín influence. Garagay, a site in the modern-day Lima region, has variations of the characteristic Chavín iconography, including a head with mucus coming from the nostrils. At the site of Cerro Blanco, in the Nepena valley, excavations revealed Chavín ceramics.
