I recently won one of Inkwell Ideas' Geomorph Mapping contests, and the prize package included two volumes of Matt Jackson's Moleskine Maps.
The maps are typically mini-dungeon size, most having 10-12 encounter areas. Each map is paired with a complementary notes page for keying the map with a brief outline of background, locations, critters, and treasure. This makes for a very usable on the fly creation format for a side adventure, ancillary area for a larger scenario, or when those pesky PCs wander off the map...
Matt's mapping is spare and clean, with features indicated but not crowding the spaces (along with the ever-popular crosshatching borders...). Plenty of information, or inspiration, is hinted at. And for being small dungeons, several have either multiple entrances, or enough tortuosity, that they aren't a bunch of one-way streets.
Matt is one of the more proficient and prolific OSR mappers. His Patreon maps include colored variants, as well as designs suitable for SF gaming, such as maps intended as futuristic bases or spacecraft interior layouts.
So, I randomly selected a map from Moleskine Maps IV, and did a evening's worth of populating and storyline creation:
