Emily did a blog entry on MOLA tracks back in August 2010 and Conception is recorded as having an elevation of -1372m relative to Mars datum. Cape Tribulation has an elevation of -1380m so at the top of the mound near Conception Opportunity was a smidgeon higher than she is now. Remember that the MOLA samples are quite sparse. Emily's post shows that there are only a few samples very close to Oppy's route. (See also this post.) So we can't be very sure what the highest elevation we reached was. Given the uncertainty about our current elevation, I think we can only say that we're within 20 m or so of our highest point. From this official DTM elevation map you can only crudely read our elevation, but you might be able to get something more quantitative from some of the other images there. Pgrindrod did some elevation maps a while back; this one gives a good overall view of how we dropped from Victoria and then climbed back up. |

Just to be absolutely sure I emailed Larry Crumpler and he confirmed that -1380 figure for the summit.

Thanks a lot ngunn.
Please, tell me if I'm wrong, but I recorded that the altitude of Opportunity's landing site is -1387m. It means that with the -1380m figure we are now just sitting slightly above the landing site, knowing that we have travelled down a slope to reach Endeavour crater... |

Yes and the latest NAVCAM of your hill (dead centre here) shows another smaller but clearer feature about 15 degrees farther to the right plus a possible faint hint of the Miyamoto rim extending between the two.

A Request: Can we please have some 'mystery men' stationed along the rim southward?

Here is a great boon for distant horizon watchers. Larry Crumpler's latest field report for 15th Jan includes a navcam panorama with an azimuth scale. The central image in the panorama is the one I linked to two posts up. This should nail the IDs of the horizon features.
http://www.google.co.uk/url?sa=t&rct=j....83829542,d.d24 EDIT: Apologies for the messy link. Maybe someone can replace it with a better one? My first rough estimates for the azimuths: charborob's hill 197, possible Miyamoto rim 205, smaller closer (around 32km) hill 210. James Canvin will tell us whether this makes any sense I'm sure. |
