NOAA's National Mussel Watch Program - which has used invasive zebra + quagga mussels to track contaminants in the #GreatLakes since 1992 - finds that PFAS are ubiquitous in the lakes, with mussels in Lake Michigan having the highest average PFAS concentrations www.bridgemi.com/michigan-env...

Study of invasive mussels finds PFAS is nearly everywhere in the Great Lakes | Bridge Michigan

A recent report that PFAS contamination is widespread in Great Lakes mussels give a clearer picture of where the chemicals are concentrated.

You can bring your bike on the South Shore Line and not ride a hundred miles to the Indiana Dunes and/or back, it's totally allowed

NPS#129 : Indiana Dunes National Park. Trails, dunes, beaches, tons of wildflowers and a bevy of bird sightings are making our trip memorable. Oh, and Bark Ranger tags!

Woohoo! It's Friday!
Indiana Dunes, midwinter. Me using the frozen dune as a giant slide. The frozen sand was essentially one long piece of sandpaper, by the time I reached the bottom my pants were shredded! 😄

Indiana Dunes, midwinter.
Pushed the ISO to add a bit of grain. I like how the lake blends into the dark cloudy sky.

I built this shoddy birdhouse for my daughter at the Indiana Dunes Birding Festival and now the birds have reported me to code enforcement.

Just got back from the Indiana Dunes Birding Festival—what an incredible experience! Grateful for the love during my Bird Joy talk, time with the Chicago BIPOC Birders, and finally meeting some Indiana Bird Nerds in the wild. #BirdJoy #WiscoBirder #WeOutHere 🗣️🐦🫶

First attempt at capturing this. Only happens during two short windows of the year. I'm so happy the planning & weather worked out!

Thanks to @victwav.bsky.social for the assistance in the cold and @cshimala.bsky.social for the inspiration/tips!

Wooden staircase leads down through sandy dunes and sparse trees at Indiana Dunes National Park, with Lake Michigan and the distant Chicago skyline visible under a clear blue sky. The winding boardwalk blends into the natural landscape of rolling hills and greenery.

The lupines at Indiana Dunes National Park are incredible this year. I had a limited time to visit but I think I made the most of it. It was a cloudy day, which disappointed me at first, but the lupines seem to glow even in flat light. 💙

The comment period for the rule change (FWS-HQ-ES-2025-0034) ends tomorrow, so it is critical that you log your objects ASAP if you have not already done so: www.regulations.gov/commenton/FW...

Stewards of the environment, please comment on the UFSWS's proposed rule change to the Endangered Species Act before tomorrow: bit.ly/44KZOwM

This rule change would remove damage to habitat from the definition of "harm" to endangered species. This is unacceptable: habitat loss = species loss.

@40doodles.bsky.social and I went to the Indiana Dunes today and it was amazing! Highly recommend this gorgeous beach and park. We climbed a very steep dune called the Devil's Slide.
