After we ran a blog post about how Lake Erie was almost completely frozen over, we got an email from Cleveland resident Mike Sutadji, who had some even more surprising news. He and his buddy Ariel Travis actually had ventured 2.5 miles out onto the ice and spent the night there in a tent, enduring temperatures that dropped to just 9 degrees Fahrenheit. They've got the pictures to prove it. After Travis, seen above, saw National Oceanic and Atmospheric Administration charts showing the ice thickness on Lake Erie, the two got inspired to venture out onto the lake's frozen surface.BLOG: Lake Erie Is Frozen, But Don't Try Hiking It
Sutadji and Travis hiked used a NOAA chart showing the thickness in various areas. "When people watched us walk out from the beach, they looked at us like we were crazy," Sutadji recalls.NEWS: Giant Summer Toxic Algae Bloom Threatens Lake Erie

At night, out on the frozen lake, Cleveland exuded an otherworldly glow in the distance. The nighttime temperature dropped to 9 degrees Fahrenheit. "Next time, we're going to bring a warmer tent," said Sutadji.Is A 17th Century Wreck Buried In Lake Michigan?
The men didn't see anyone else out on the frozen lake. They had cellphones to keep in contact with people on land, and a small supply of provisions -- canned tuna, beans and mandarin oranges.What Warming Means For Lake Effect Snow
Greenpeace said Monday that hazardous chemicals were "widely present" in a range of outdoor gear it tested, from clothing and footwear to backpacks, tents and sleeping bags
The environmental activist group said out of 40 products tested, only four were free of per- and polyfluorinated chemicals (PFCs).
The study showed that toxic chemicals are "still widely present in products by brands such as Jack Wolfskin, The North Face, Patagonia, Mammut, Norrona and Salewa, especially in the production of footwear, trousers, sleeping bags and some jackets," said the report.
PFCs are used to add waterproof and dirt-repellent finishes to outdoor apparel, but are hazardous to the environment and human health, said Greenpeace.
"Once released into the environment most PFCs break down very slowly. They can remain in the environment for many years after their release and are dispersed over the entire globe," the report said.
The pollutants have been found in secluded mountain lakes and snow, can accumulate in the livers of Arctic polar bears and be detected in human blood, the report said.
Greenpeace said studies had shown that some PFCs "can cause adverse impacts ... on the reproductive system and the immune system, as well as being potentially carcinogenic in animal tests."
The group said an independent laboratory had tested 11 jackets and eight trousers, seven pairs of shoes, eight backpacks, two tents, two sleeping bags, one climbing rope and one pair of gloves.
The four products that did not contain PFCs were jackets by Vaude and Jack Wolfskin, a backpack by Haglöfs and a pair of gloves by The North Face, said Greenpeace, adding that this showed it is possible to produce outdoor gear without PFCs.
The group urged all outdoor apparel companies to join its 'Detox My Fashion' campaign that aims to quickly remove hazardous chemicals from the entire manufacturing supply chain of the textiles industry.
"Phasing out PFCs by 2020, as some outdoor clothing brands aspire to do, is not ambitious enough," the group said.
"It is not acceptable that their products continue to release persistent and potentially hazardous chemicals into the environment for another five years."
