Peer Review
For the La Reforma Caldera paragraph it's a bit choppy. There are sentences there that can either be restructured or combined to make it flow much better. Also, citations are need for the end of the last sentences. If you can find a citation for the landscape that would be great too!

Viewpoints
I believe the viewpoints are a little underpresented. Yes the articles break into three different volcanoes in baja california but there are not subsections. I would of expected a bit more geographic information of each volcano. For example the Tres Virgenes article is well represented and La Reforma Caldera is underrepresented. The article describes the articles to a minimum.

1. https://www.britannica.com/place/Baja-California-peninsula-Mexico From this article I will include the geography of Baja California in general so the people reading the article have a sense of the area where the volcanoes are locate. I will include that the peninsula is roughly 760 miles long and along this there are several different volcanoes. The article says that the last eruption for Las Tres Virgenes was in 1746. There can be some other geography information including the three different climate zones.

2. https://earthobservatory.nasa.gov/IOTD/view.php?id=36205 From this article it is said that the volcanoes from northeast to southwest get bigger and younger. It gives information about La Virgen volcano ( type of eruption, the flow). It also gives information about the eruption type of the Las tres Virgenes volcano.it consists of pyroclastic rocks. I can maybe then define pyroclastic rocks and the dangers that come along with them. From both articles I can discuss how some of Baja California's geography contributes to the volcanoes and where they lie.Mgh972103 (talk) 05:32, 17 April 2017 (UTC)

First Draft Edits

The Tres Virgenes refers to three volcanoes that lie along the NE-SW and as they continue to go SW they are younger. La Virgen, having the highest peak as well as being the youngest among the three, has a large amount of dacite lava domes along with flanks that have a lava flow, thus causing it to be an andesitic stratovolcano. El Viejo, hence its name, is the oldest lowest peak The Tres Virgenes has a tectonic setting of rift zones that are more than 25 km deep within the continental crust. There are stratovolcanoes, lava domes, and pyroclastic cones, from these volcano types forms several rock types but some major ones are andesite, basaltic andesite, and dacite rocks. Dacitic lava domes and flows are composed inside El Viejo and El Azufre.

Unlike other volcanoes in Baja California, the Tres Virgenes are known for some of the largest stratovolcanoes, meaning that they have layers of erupting products that continue to pile up. While it has the largest, the last time the volcano was active was in 1746 with a possible eruption in 1857. The evidence for the 1746 eruption came from a Spanish Priest, who at the time was on a navigation in the Gulf of California. He reported there being an ash plume from the effusive eruption, and while no tephra deposits have been discovered, there is evidence of andesitic lava flow that could have came from the 1746 eruption.

Considering La Virgen is the youngest volcano, it has had a complex long list of volcanic eruptions. Is has had a history of pumice eruptions, explosive eruptions consisting of pyroclastic flows, dacitic and andesitic lava flows.

Review
Your post had solid detail and information about the volcanoes, however your post contains grammatical errors. You have run on sentences, so I would correct those too. For example: "La Virgen, having the highest peak as well as being the youngest among the three, has a large amount of dacite lava domes along with flanks that have a lava flow, thus causing it to be an andesitic stratovolcano." I would rewrite this as "La Virgen has the highest peak and is the youngest among the three volcanoes. It contains a large amount of dacite lava domes along with flanks that have a lava flow which causes it to be an andesitic stratovolcano." Other than proofreading and making sure your post if free of grammatical errors and sentences are structured better, you have a great post. Iloveolivine! (talk) 02:31, 2 May 2017 (UTC)

La reforma Caldera is a volcano that is on the east-central Baja california. It is about 10km in diameter and at about an elevation of 4264 ft. In the east-central Baja california there are several volcanoes and this one lies east of the Tres Vírgenes volcano and SE of El Aguajito. There are several things that distinguishes the differences between these volcanos and one of the things are the type of volcano it is and the kind of rocks it contains. La reforma is a caldera volcano meaning that it is one of the volcanoes that form in a way where it collapses into an empty magma chamber forming something that looks like a crater. A caldera volcano is one of the most dangerous for the fact that the eruptions are huge of about 100-1000km^3 of material. La reformas last huge explosive was recorded about 10,000 years ago. It has been recorded that La reformas eruptions have consisted of ash and pumice falls, pumice flows, and pantellerite tuffs.

1st Draft: El Aguajito also known as Santa Ana caldera, is located North-East of Las Tres Virgenes. It's latitude is at 27.554*N and a Longitude of 112.552*W. El Aguajito was formed p.06 million years ago due to eruption if ignimbrites [1]. The rim of the caldera is approximately 10-km wide and is not exposed to the surface. There is an active geothermal system with hot springs on the southern side of the caldera. The first eruption is dated 7600,000 years ago, the latest eruption date is unknown [2].

1st Draft Edit GEOGRAPHY Physical features Baja California is a peninsula in Mexico, bordering the Pacific Ocean and the Gulf of Mexico. It is made up primarily of mountains, and some coastal plains. The mountain ranges in Baja California, connected to the Pacific Coast Ranges, extend from the north-eastern to the south-western part of the peninsula. Out of the 24 named ranges, the Sierra de Juárez and the Sierra San Pedro Mártir, the highest range in Baja California, are the two most significant. The slopes of the ranges vary depending on location; the slopes on the western side are gentler than those on the east. Coastal plains are mostly found in the south-west regions on the peninsula. In the center of Baja California, volcanic activity is found mostly near the San Ignacio area. [1] Rivers The majority of the rivers and streams in Baja California, such as San Benito, San Miguel and Raymundo, lead back to the Pacific Ocean. The San Ignacio River, however, which is the longest river in the peninsula, leads to the Ballenas Bay. Climate In general, Baja California’s climate is hot, dry, and mainly desert. The north and the south receive much more rain than the central regions, which only occasionally receive a small amount of rain in the summer while staying mostly dry. As for the coasts of the peninsula, temperatures on the west are very different than those of the east. Due to the cold water coming from the north with the California Current, the west coast is much cooler than the east and south, which stay rather warm in the winter time as well.

Peer Review
I like how each volcano was briefly described but I would love to know more information on each volcano as to how active are they. super active? just simple information so that readers know more about the volcanoes also give some interesting facts on how it got its name or why this volcano in specific is interesting. definitely more information on each volcano would be great also a simple description on to how they all relate or connect it to other volcanoes and give examples. The geography section could use more description to give readers a visual view of what it looks like add more to what there currently is. Good job overall just need some more information hope this helps. — Preceding unsigned comment added by Pup shilo (talk • contribs) 23:41, 1 May 2017 (UTC)

Overall this was a good article there was only a couple of things that could have been added to make the article a little more interesting. I would have like to see more pictures of the volcanoes, this would have added more of a visual effect to the article. Something else that could have been added would be more citations, also their were some grammatical errors. Like I stated above this article was good over all, the information added was relevant and interesting. Katy1996 (talk) 07:06, 3 May 2017 (UTC)

Peer review: needs more citations
The article seems very interesting, but you need more information, the article has a lot room for improvement. There is barely any sources in this article, this makes it seem not creditable. I suggest more research on these different mountains and adding even the little details that can come with the information. Overall, it's at a great place to start but it needs more information and sources.MidoriWolf07 (talk) 03:24, 2 May 2017 (UTC)midoriwolf07
