#30DayMapChallenge Day 25: Hexagons
Hexagons have a unique visual quality that (for many) they just 'feel' better then regular grids/cells. This map looks at # of bridges in the shape and visually compare hexagons vs rectangles. Explore at: damian.maps.arcgis.com/apps/instant...

Day 15 of the #30DayMapChallenge yeah I know I'm late and also that the theme of the day was "fire" not ice.
But, hey, snow and ice can burn too—and so can anger at neighbors who don't shovel their walkways. Here are contours of 311 calls in Boston for "unshoveled snow."

One of the unexpectedly cool things about rafting though the Grand Canyon was the velvet ants
Arizona velvet ants are colorful little insects that will DESTROY you. Their sting is described as 'hot oil from the deep fryer'. As wingless wasps, they will drop you to your knees. They will make you call to god. They are the reason countless children are afraid of cute insects.
they are perfect

A female wolf has been doing something unusual on the Central Coast of British Columbia. She's learned to pull crab traps up from the water, yanking on a rope to bring it to the surface. But is it tool use? Very fun story from @phiejacobs.bsky.social for @science.org
Have wild wolves learned to use tools?
Video captures a lone female pulling crab traps out of the water, but does it count as tool use?

This visualization of Japan’s M6.8 yesterday is phenomenal. Offshore S-net detected it and issued earthquake alert before any land station detection. Numbered circles show JMA intensity (not same as MMI). Offshore is where we need to be in Cascadia as well.
The underwater seismometer network is so great, as evidenced from yesterday's EQ off-Tohoku.

Edinburgh is a wonderful city. And it is generally accessible, however as with any city, some parts are more accessible than others. This map uses data from ArcGIS Online to show the accessibility score by postal codes.
