Did you notice that prairie dogs make this area their home? They like to make chirping noises to warn each other of people in the area, so they are difficult to miss! What they are also doing is trying to make future trace fossils. A trace fossil is a record of life that isn’t the animal or plant itself, but is a sign that life was there – such as a footprint or burrow. Not all footprints or burrows will be preserved in rock, but some will be preserved as trace fossils. If conditions are right, some prairie dog burrows may be preserved in the rock record.<br /> <br /> So, will the volcano erupt again? Well, it is possible! We know there is still magma about 4.5 miles beneath part of the Preserve. When might it erupt? Good question – we don’t know, but we do know that there would be plenty of warning signs first, so no eruption today, or this month. If the volcano wakes up again, it will let us know! There would be lots of small earthquakes, and the ground temperature and the temperature of water in the springs would increase. There would be lots of excitement at Valles Caldera National Preserve as scientists rush to study it!<br /> <br /> This is the end of the Cerro La Jara Trail tour. We hope you learned some interesting facts about the geology of this beautiful Preserve.<br /> <br /> <br /> <meta charset="utf-8" /> <p dir="ltr"><em><b id="docs-internal-guid-25f0e0b0-7fff-bf6e-7943-4b593ec45b98">¿Te has dado cuenta de que los perros de la pradera han hecho de esta zona su hogar? Les gusta emitir chirridos para avisarse unos a otros de la presencia de personas en la zona, ¡es difícil no verlos! Lo que también están haciendo es intentar crear futuros fósiles de huellas. Un fósil de huellas es un registro de vida que no es el animal o la planta en sí, sino una señal de que hubo vida allí, como una huella o una madriguera. No todas las huellas o madrigueras se conservarán en la roca, pero algunas se conservarán como fósiles de huellas. Si las condiciones son adecuadas, algunas madrigueras de perros de la pradera pueden conservarse en el registro rocoso.</b></em></p> <p dir="ltr"><em><b id="docs-internal-guid-25f0e0b0-7fff-bf6e-7943-4b593ec45b98">Entonces, ¿volverá a ver una erupción volcánica? ¡Bueno, si es posible! Sabemos que todavía hay magma a unos 7,2 km bajo parte de la reserva. ¿Cuándo podría entrar en erupción? Buena pregunta, no lo sabemos, pero sí sabemos que primero habran muchas señales de advertencia. Por eso sabemos que no habrá erupción hoy ni este mes. Si el volcán vuelve a despertar, ¡nos lo hará saber! Habrían muchos pequeños terremotos y la temperatura del suelo y del agua de los manantiales aumentaría. ¡Habría mucho entusiasmo en la Reserva Nacional Valles Caldera, ya que los científicos se apresurarían en venir a estudiarlo!</b></em></p> <p dir="ltr"><em><b id="docs-internal-guid-25f0e0b0-7fff-bf6e-7943-4b593ec45b98">Aquí termina el recorrido por el sendero del Cerro La Jara.

Look northward across the road. The broad valley is Valle Grande. A lake filled this valley several times in the past. If the lighting is right, you will be able to see low, flat lying ridges at the base of the mountains in the distance. These ridges are sediments that were de…

At the entrance station, we are surrounded by montane grasslands. Across the road is a small, forested lava dome called Cerro La Jara. If you're looking for a short hike with lots of wildlife watching opportunities, there's a wonderful 1.4-mile loop trail around the lava dome.…

<p>As you walked, you probably noticed that you are walking in a large valley and there are rounded hills or mountains in the distance, behind you, and to your right. You are walking in a volcanic caldera – a depression formed during a volcanic eruption. This caldera was forme…

Cerro La Jara Stop 4
~1 min drive
Look straight down the path. Cerro La Jara is to your right and South Mountain is directly in front of you. Both of these formations are volcanic domes. Volcanic domes are formed by the extrusion of lava that piles up in a dome shape. Cerro La Jara and South Mountain were form…

So far, you have learned that about 1.2 million years ago, a giant volcanic eruption occurred and created Valles Caldera when the roof of the empty magma chamber collapsed. The material that was erupted (called the Bandelier Tuff) was deposited inside the new hole in the groun…

The large mountain in the distance directly ahead of you is Redondo Peak. The smaller peak just to the right is Redondito. These mountains are part of a resurgent dome in the center of Valles Caldera. A resurgent dome is different than a volcanic dome; it wasn’t extruded as la…

The Movie Set Cabin
~2 min drive
Located on Valles Caldera's main entrance road, approximately a half mile from NM State Route 4, this cabin is part of the 2003 "The Missing" movie set starring Tommy Lee Jones and Cate Blanchett. Park at the Jemez River Trailhead and walk a quarter mile up the trail beyond th…

Saddle Shed
~2 min drive
The saddle shed, also known as the tack shed, was built in 1963 to serve ranch operations. Ranch hands started their days here, grooming their horses and saddling up before sunrise. They would ride up to 20 miles a day, checking on livestock, inspecting fences, and tending to…
