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.
