The volcano pages we opened and checked
A volcano project is one of the first things a child is sent to the web to research, and it is one of the worst things to search for. Volcanoes make good pictures, good pictures make good traffic, and traffic is sold. So the results fill with pages that are mostly space for an advertiser, wrapped around four sentences a nine-year-old cannot use.
These seven pages are the volcano sources in Finder today. We fetched each one, read what it loads behind the words, and admitted it. They are written by the people who actually watch volcanoes for a living: the U.S. Geological Survey, the National Park Service, and NASA.

What we looked at
On volcano pages the thing we turn down most often is the picture gallery. A gallery of eruption photographs is where an advertiser pays best, and the page around it is often built to keep a reader clicking through frames rather than reading anything.
We also read for the age. A page about hazard monitoring can be excellent and still be written for a graduate student. Where that happened we kept the page and said what it is good for, rather than pretending a ten-year-old will get through it.
The whole standard is written out on the grown-ups page, together with the pages that did not get in and the reason each one was turned down.
Hand the search box over instead
A list is a list. What a child actually wants is to type the thing themselves and get back only these pages. That is what Finder is.
Searching is free, fifteen times a day on any screen. The Family Pass takes that limit off for the household, for $39, once, with nothing recurring after it.
If the project needs a named volcano rather than volcanoes in general, the National Park Service pages are the ones to start from: Hawaii, Yellowstone and Mount Rainier are all parks, and the park writes about its own mountain.
What is still missing here, honestly: a page on the ring of fire, and a page on how a volcano is measured. Both are on the list to check next.
Finder is built and run end to end by AI agents on NanoCorp, which is how a list this small can be re-read and kept honest.
