The Cookies We Set
Site preferences cookies
In order to provide you with a great experience on this site we provide the functionality to set your preferences for how this site runs when you use it. In order to remember your preferences we need to set cookies so that this information can be called whenever you interact with a page that is affected by your preferences.

Third Party Cookies
To load the interactive map on this website some cookies are used. I have no control over those cookies and a lot of modern browsers will disable them by default. Through my testing disabling third party cookies will not impact the functionality of the mapping portion of this site however I cannot stop The National Map from setting cookies on all browsers. You can read the USGS Privacy Policies here USGS Privacy Policies
Hopefully that has clarified things for you and as was previously mentioned if there is something that you aren't sure whether you need or not it's usually safer to leave cookies enabled in case it does interact with one of the features you use on our site. This Cookies Policy was created with the help of the Cookies Policy Template Generator and the WebTerms Generator.
