The United States Geological Survey published composite maps and data for the country’s geological makeup.
The Earth’s Surface geology layer depicts geologic units exposed at the Earth’s surface in the conterminous United States, ranging in age from Quaternary glacial deposits and alluvium to Precambrian crystalline bedrock. In the U.S. West and Southeast, the map is a composite of 29 state geologic maps depicting geology at the Earth’s surface. In the glaciated region of the Midwest and Northeast, the map is a composite of 21 state geologic maps depicting pre-Quaternary rocks (“bedrock”), 8 state geologic maps depicting Quaternary deposits, and 18 USGS Quaternary Atlas Series maps depicting Quaternary deposits. The Quaternary Atlas maps were used where modern state geologic maps were not available.
You can download the data and other map layers through USGS. As per the title, the above only shows the surface. They have data that stretches back billions of years ago.

Reddit user ViKoToMo scraped Costco receipts from his account and made a dashboard that shows spending for the past two years.
This short script by Ankur Dave was used to access Costco receipts. I’m not sure how long that’s going to work, but there you go, in case you also would like to see how many thousands of dollars you spend on organic chicken thighs, bananas, and street tacos.

Speaking of traffic fatalities, Helsinki is doing things differently. Amanda Shendruk for Not-Ship has the charts:
This past summer, Helsinki made an astonishing announcement: as of August, the Finnish capital went an entire year without any traffic deaths. Not a single pedestrian, cyclist or driver died on the city’s roads. Not. One.
And this wasn’t an outlier year. Helsinki’s traffic deaths have been steadily declining for decades.
Lower speed limits and income-based speeding fines helped the city get to this point. Maybe others should give this a try.
Sidenote: Not-Ship is a new data-focused newsletter from Shendruk that is worth a sub.

For the Washington Post, Ian Duncan, Emmanuel Martinez, and Dylan Moriarty analyzed traffic fatality data from the National Highway Traffic Safety Administration:
The Post analysis documents, for the first time, a sharp increase in places with clusters of pedestrian deaths, revealing the deadliest neighborhoods and stretches of road in hundreds of cities. The number of locations with at least three recent pedestrian deaths clustered within a mile of one another tripled during this period, from more than 275 in 2010 to more than 825 in 2023, The Post found. Those hot spots increased most in states in the southern half of the country such as Tennessee, North Carolina and Arizona.
A searchable map lets you see incident counts in places of interest, which is unsettling when you see dots and hexagons not far from where you live.

Is your salary high, low, or somewhere in the middle? What do people with higher salaries than you do for a living? Doctors, lawyers, and tech workers come to mind, but there is a wider range of occupations, depending on the income level you’re comparing against.
