This compilation of synonyms and subsidiary features may not be comprehensive. Features are organized into four major categories: Cones, Craters, Domes, and Thermal Features. Synonyms of features appear indented below the primary name. In some cases additional feature type, elevation, or location details are provided.

|Negit Island, capped by the dark-colored cinder cone at the right, was the source of one of the most recent eruptions of the Mono Lake volcanic field. Rhyodacitic lava flows overlie a 1240 AD tephra unit. The light-colored tufa deposits near the western shore of Mono Lake in the foreground were created by deposition of calcium carbonate beneath the waters of the lake.

|Paoha Island in the center of Mono Lake at the left is seen from the flanks of Panum Crater on the south, at the northern end of the Mono Craters. The Mono Lake volcanic field consists of multiple volcanic vents on the northern shore of the lake and on Paoha and Negit Islands, which were last active a few hundred years ago.

|The Mono Lake volcanic field consists of rhyolitic lava domes and flows, phreatic explosion craters, and cinder cones on islands in Mono Lake and on its northern shore. This view shows explosion craters on Paoha Island, with the Mono Craters dome complex and the Sierra Nevada in the distance to the south. The ages of the most recent eruptions of the Mono Lake volcanic field range from about 2000 to about 200 years.

|Negit (right-center) and Paoha (far right) islands in Mono Lake are seen from Black Point, a basaltic cone on the NW shore of the lake. The most recent eruptive activity from the Mono Lakes volcanic field took place 100-230 years ago, when lake-bottom sediments forming much of Paoha Island were uplifted by intrusion of a rhyolitic cryptodome. Black Point is an initially sublacustral cone that formed about 13,300 years ago when the lake was higher. The White Mountains form the far right horizon.

A listing of samples from the Smithsonian collections will be available soon.
|Large Eruptions of Mono Lake Volcanic Field||Information about large Quaternary eruptions (VEI >= 4) is cataloged in the Large Magnitude Explosive Volcanic Eruptions (LaMEVE) database of the Volcano Global Risk Identification and Analysis Project (VOGRIPA).|
|WOVOdat||WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.|
|EarthChem||EarthChem develops and maintains databases, software, and services that support the preservation, discovery, access and analysis of geochemical data, and facilitate their integration with the broad array of other available earth science parameters. EarthChem is operated by a joint team of disciplinary scientists, data scientists, data managers and information technology developers who are part of the NSF-funded data facility Integrated Earth Data Applications (IEDA). IEDA is a collaborative effort of EarthChem and the Marine Geoscience Data System (MGDS).|
|MODVOLC - HIGP MODIS Thermal Alert System||Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.|
|MIROVA||Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.|
