Quilotoa
Template:Short description Template:Infobox mountain Template:Volcanoes in Ecuador Quilotoa (Script error: No such module "IPA".) is a water-filled crater lake and the most western volcano in the Ecuadorian Andes. The Script error: No such module "convert".-wide caldera was formed by the collapse of this dacite volcano following a catastrophic VEI-6 eruption about 800 years ago, which produced pyroclastic flows and lahars that reached the Pacific Ocean, and spread an airborne deposit of volcanic ash throughout the northern Andes.[1] This last eruption followed a dormancy period of 14,000 years and is known as the 1280 Plinian eruption.[2] The fourth (of seven) eruptive phase was phreatomagmatic, indicating that a Crater lake was already present at that time.[3] The caldera has since accumulated a Script error: No such module "convert". crater lake, which has a greenish color as a result of dissolved minerals. Fumaroles are found on the lake floor and hot springs occur on the eastern flank of the volcano.[1]
Quilotoa is a site of growing popularity. The route to the "summit" (the small town of Quilotoa) is generally traveled by hired truck or bus from the town of Zumbahua Script error: No such module "convert". to the South, or more commonly by bus from Latacunga. Visitors have to pay two US dollars each to enter Quilotoa. There are a number of simple hostels in the immediate area offering services such as mules and guides. Activities include a four to five-hour hike around the caldera (whose diameter is just over Script error: No such module "convert".). The caldera rim is highly irregular and reaches its maximum elevations Script error: No such module "convert". to the N, Script error: No such module "convert". to the NW and Script error: No such module "convert". to the SE, at three lava domes. The Script error: No such module "convert". hike is sandy and steep in places and can be quite taxing, particularly if there is fog.
It is a half-hour hike down from the viewpoint (and 1- to 2-hour hike back up the Script error: No such module "convert". vertical ascent), and very basic lodging down in its bowl. Camping is permitted at the bottom of the crater, but there is no potable water (except half-litre bottles sold at the hostel)[4]
The lake surface is located at Script error: No such module "convert". asl. The total volume of water stored in Lake Quilotoa is Script error: No such module "convert".. According to local inhabitants, the lake level has been slowly declining over the last 10 years. Travertine deposits occur along the shore up to Script error: No such module "convert". above the lake level (in the year 2000).[3]
The village of Quilotoa and the associated crater is also a popular destination within the Quilotoa Loop and is a common starting point for the “Quilotoa Traverse”, a multi-day village to village hiking route.
