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...

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

Got myself a Nikon Coolpix P950 for a trip overseas…tested it out this past weekend at Indiana Dunes National Park and captured this tree swallow from a ways away.

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! 😄 #indianadunes #naturephotography #nature #blueskyphotographers #photography #indiana

Indiana Dunes, midwinter. Pushed the ISO to add a bit of grain. I like how the lake blends into the dark cloudy sky. #Indiana #indianadunes #bnw #photography #nature #naturephotography #lakemichigan #photographersofbluesky #blueskyphotographers

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

Chicago skyline post sunset from the Indiana Dunes. I think next time I'll come prepared with a second camera for photos during the sunset! #chicago #skyline #sunset

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 🗣️🐦🫶

Some #birding highlights from the Indiana Dunes Birding Fest <3 I'm only using my phone camera so quality isn't the best but!! Saw some good good birds

A record 970,000 Hoosiers are expected to travel this Memorial Day weekend, kicking off the busy summer travel season and bringing visitors back in droves to the Indiana Dunes.

Chicago skyline sunset from the Indiana Dunes. 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!

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. 💙 #indianadunesnationalpark #lupines #photography #spring

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.

Had a rough start to the day with some Joy Jackers, but my Bird Joy got refilled co-leading two BIPOC-only hikes with the Chicago BIPOC Birders at the Indiana Dunes Birding Festival. Birds, community, joy… and treats (they disappeared fast). We a whole VIBE! #BirdJoy #IndianaDunesBirdingFestival 🪶

There are about 800 bird species in the United States. Nearly half of them live in or migrate through the Indiana Dunes.

At the Indiana Dunes Birding Fest. At the Longshore tower, they counted over 1000 blue jays this morning!

Had two amazing evenings with moths at Indiana dunes birding festival. Here are some highlights...

What’s up, Indiana? Where are your favorite birding spots near the Dunes? It’s my first time at the Indiana Dunes Birding Festival. I need help from the Bird Nerd Homies. @indiana-dunes.bsky.social @indianaaudubon.bsky.social 🪶

Hundreds of birders from all over country are flocking to the Indiana Dunes Tourism Festival this weekend, celebrating Northwest Indiana's role as a migratory hotspot.

The cool breeze off #lakemichigan. Waves crashing along the sandy dunes of #indianadunesnationalpark. This is the view at the end of the Dune Succession Trail 🌊 On a clear day, you can even see Chicago’s skyline way off in the distance! #nationalparks #nature #photography #travel #hiking #explore

Following a pause on the construction of the invasive carp barrier at the Brandon Road Lock and Dam that's lasted since February, it now looks like things will be moving forward to help protect the #GreatLakes abcnews.go.com/US/wireStory...

Quick weekend trip to #indianadunes! Met up with my parents, hiked with the pups & learned about Diana of the Dunes. Can’t believe we hadn’t heard of her before! 📷 West Beach with Lake Michigan stretching wide & Chicago in the distance. #hiking #indiana #nature #photography #travel #nationalparks

Big thread on the Morse Code house. First off - to set the scene - this now demoed house was well known and well viewed - on one of the most traveled routes in the Indiana Dunes National park. Most locals knew about it, but didn't know much about the *why*, myself included. This got me curious. 1/7

Wetlands of Chicago's Calumet region, on the city's southeast side, have long faced degradation by surrounding industry. While lots of progress has been made in their restoration, there are still threats - namely climate change and the loss of wetland protections news.wttw.com/2025/05/09/s...

ICYMI, we're on the road this week. Catch us at the Biggest Week in American Birding #bwiab until Tuesday evening. Then, we'll be at the Indiana Dunes Birding Fest Thursday through Sunday. If you're at either event this week, be sure to say hello! 🐡🎨🪶
