https://pnwherbaria.org/
The Consortium of Pacific Northwest Herbaria is a collaborative portal uniting 60 regional herbaria across Alaska, British Columbia, Oregon, Washington, Idaho, Montana, and the Yukon, offering access to over 3.6 million plant specimen records and nearly 1.8 million images. Researchers and naturalists can search the database by label data or geographic location, download datasets for offline use, and consult a fully annotated checklist of vascular plants native to the Pacific Northwest.
https://mm4rk3t.neocities.org/
A minimalist personal page from a creator known as mm4rk3t, built around a Latin aphorism about stars being visible only at night and the sleepless nights that make mathematicians and astronomers. The sparse, cryptic aesthetic and classical quotation give the site an enigmatic, philosophical quality that hints at interests in astronomy and mathematics.

The Quincy Area Repeater Group (QARG) was a club of licensed amateur radio operators in West Central Illinois who established and maintained the 147.195MHz 2M repeater serving the Quincy, Illinois and North Eastern Missouri area. The site serves as a historical record of the group's 18-year operation before transferring control to the Western Illinois Amateur Radio Club, including a full list of charter members and their callsigns.

Hosted by the University of Washington's Atmospheric Sciences department, GRAYSKIES is an educational resource focused on Earth's atmosphere, offering climate data, rooftop weather observations, and curated links to Pacific Northwest weather and climate tools. Visitors can explore 30-year climate averages, satellite imagery, and data plotting tools alongside a broad collection of regional and national weather resources.
https://k7su.com/
Kelly Klaas (K7SU) runs this personal hub covering amateur radio, handmade Morse code keys, woodworking, laser engraving, and voice-over work. The site serves as a launchpad to several distinct projects, with the handmade keys and ham radio content being the clear centerpiece.
http://rfchoke.com/
A technical reference site dedicated to RF chokes, ferrite cores, and related radio frequency electronics components used in amateur radio and RF engineering applications. Visitors will find practical information on choke design, impedance characteristics, and suppression of common-mode currents on antenna feedlines.
https://frankdeboosere.be/klimaatukkel/klimaatjuni.php
Belgian meteorologist Frank Deboosere presents detailed interactive climate charts for Uccle, Belgium, tracking temperature, precipitation, and sunshine duration across decades. The graphs plot 30-year rolling averages against current normals, making long-term climate trends and changes visually accessible to anyone curious about local Belgian climate history.
