Thin on the right so far
None of the 13 outlets with a published leaning rating that ran this story are rated right.
This story is still being watched, so it is a count and not yet a finding. Coverage keeps arriving for hours after an event, and a side that has published nothing this morning may publish by tonight. If it is still true when we stop checking, we will say so plainly.
Search and rescue responders extricated a caver from Rats Nest Cave in Canmore, Alberta, on August 15, 2026. The caver had become trapped in a difficult vertical passage known as the "psych squeeze." The rescue operation involved 13 cave rescuers, 10 firefighters, and two Kananaskis Mountain Rescue members. Canmore Fire Rescue provided in-cave paramedics. The operation was coordinated with the RCMP.
During the rescue, responders deployed the QDX-M, a volunteer-built underground radio system, for its first live use. This technology is designed to send signals through rock in areas where conventional communication methods like cell phones, satellite messengers, and GPS do not function. Progress in freeing the caver was measured in inches per hour, with responders working to manage exhaustion, hypothermia risk, and body compression.
The caver was freed from the squeeze at approximately 10 p.m. and exited the cave at 11:46 p.m. after a period to recuperate. Other rescuers left the cave by midnight. The caver required no further medical attention, according to SAR.
Coverage comparison
What the coverage left out
None of the right-rated outlets ran this story. The digests from the left and centre-rated outlets did not mention the specific details of the rescue, such as the number of rescuers involved or the technical specifications of the QDX-M radio system, as these were summaries of broader news.
Still developing. We have re-checked which outlets are covering this 4 times, most recently on 21 Aug 2026, 10:15, and will add the sides that appear.
How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
7 rated outlets
- Seven left-rated reports carried details of the cave rescue. All seven were digests from The Canadian Press, and none contained original reporting or specific wording from the outlets themselves. These digests focused on a roundup of national news, with the Alberta cave rescue being one of several items mentioned. The digests did not provide specific details about the rescue operation beyond its inclusion in a list of news items.
Centre
6 rated outlets
- Six centre-rated reports covered the cave rescue. All six were digests from The Canadian Press, similar to those on the left. These digests presented the Alberta cave rescue as part of a broader news summary. The digests did not offer unique insights or specific details from the outlets' own reporting.

Questions about this coverage
- How did the left and right cover Caver freed from Alberta cave using new underground radio?
- Of the 13 outlets on this story carrying a published leaning rating, 54% are rated left, 46% are rated centre, 0% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it. The sections above set out what each side emphasised, in its own terms.
- Is Caver freed from Alberta cave using new underground radio left or right?
- Neither side dominates it. Of the 13 rated outlets on this story, 54% are rated left, 46% are rated centre, 0% are rated right, and no side holds the 70% this site would want before calling a field one-sided. A story is not left or right in any case; the outlets that carried it are what carry ratings.
- Is the coverage of Caver freed from Alberta cave using new underground radio biased?
- Caver freed from Alberta cave using new underground radio is one event reported by 13 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which side is not reporting Caver freed from Alberta cave using new underground radio?
- When we first saw this story, outlets rated right had barely covered it. Coverage accretes for hours after an event, so that is where to look rather than a verdict — the split above is the current count, and it is the one to read.
- Which outlets covered Caver freed from Alberta cave using new underground radio?
- 13 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- When did the caver get rescued from Rats Nest Cave?
- The caver was extricated from Rats Nest Cave in Canmore, Alberta, on August 15, 2026. The rescue operation concluded with the caver exiting the cave at 11:46 p.m. that night after being freed from a tight passage.
- What new technology was used in the rescue?
- A volunteer-built underground radio system called QDX-M was deployed for the first time during the rescue. This technology is designed to transmit signals through rock, functioning in areas where other communication devices fail.
- Who was involved in the rescue operation?
- The rescue involved 13 cave rescuers, 10 firefighters, and two Kananaskis Mountain Rescue members. The operation was coordinated with the RCMP, and Canmore Fire Rescue provided in-cave paramedics.
