Winter is Coming: An Open Data Guide to America’s Hotsprings

Hot springs are awesome. The idea of soaking in toasty, nutrient-rich water sounds good just about anytime. And with winter coming, it’s prime time for a pilgrimage to one of nature’s spas. But the online resources available leave a lot to be desired. That’s why I decided to organize all of America’s hot spring data under one roof.


The data is sourced from the NOAA’s National Geophysical Data Center by way of the 90s-era Deep Creek Hotsprings database. I used to easily scrape the data before loading it in Mode Analytics and to visualize. Because water temperature for most hot springs was provided, I decided to make it easy to filter the results by Warm (below 90 F), Hot (90-105 F) and Boiling (anything above 105 F). Once you drill down on an individual data point, you can also find out how to visit each spring by clicking the ‘Directions’ link in the table.



As you can see in the chart below, California, Nevada, and Utah have the most amount of hot and warm springs.  ie., places you can actually swim in without dying.


I’m pleased to continue to build on the outdoor adventure map that I originally launched as part of the State and National Parks post from earlier this year. Now, in addition to hot springs and park activities, you’ll also be able to discover swimming holes. If you have any ideas for additional fields, drop me a line on Twitter @sethteicher.
