THE GEOMETRY OF CHASMA BOREALE, MARS USING MARS ORBITER LASER ALTIMETER (MOLA) DATA: A TEST OF THECATASTROPHIC OUTFLOW HYPOTHESIS OF FORMATION Kathryn E. Fishbaugh 1 and James W. Head III 1 , 1 Brown University Box 1846,Providence, RI 02912, kathryn_fishbaugh@brown.edu, james_head_iii@brown.eduIntroductionChasma Boreale is a large reentrant in the northern polar layered depositsof Mars. The Chasma transects the spiraling troughs which characterizethe polar layered terrain. The origin of Chasma Boreale remainsa subject of controversy. Clifford [1] proposed that the Chasma wascarved as a result of a jökulhlaup triggered by either breach of a cratercontaining basal meltwater or by basal melting due to a hot spot beneaththe cap. Benito et al. [2] suggest an origin in which catastrophic outflowis triggered by sapping caused by a tectono-thermal event. A similarorigin is proposed for Chasma Australe in the Martian southern polarcap [3].Until accurate topographic data became available with the use of theMars Orbiter Laser Altimeter (MOLA), the topographic geometry of theChasma and its distal deposit regions had been poorly understood. Thisstudy utilizes MOLA data to describe the topography of the Chasma anddistal deposits and uses these observations to better constrain the viabilityof a catastrophic outflow method of formation as well as to comparewith terrestrial jökulhlaup features.Further study will include using the topographic data to better understandthe specific features predicted to result from the trigger mechanismsproposed by Clifford [1] and Benito et al. [2]. If Clifford’s modelapplies, topographic data should provide evidence for an initially smallChasma enlarged by frictional melting and eventually reaching the surfaceof the cap [1]. In addition, ice chunks resulting from the catastrophicflow would be later sublimed, leaving behind sediment to bemodified by eolian erosion which should be evident in the topography[1]. If Benito et al.’s model applies, the largest of the described floodfeatures should be evident in the topography such as giant current ripplesand inner channels as well as evidence for tectonic control such asorthogonal cliffs and straight walls [2]. Benito et al. suggest that evidenceof sapping would be later destroyed by outflow [2].ObservationsGeneral topography: The acquisition of new topography data fromMOLA has allowed the creation of a modified topographic map ofChasma Boreale (Fig. 1). According to Benito et al.’s model [2], thelinear shape of the Chasma is best explained by a tectonically-controlledorigin. Fig. 1 does show a generally linear southeast-facing wall untilabout 55°W, but there it begins to curve eastward. The slopes on eitherside of the Chasma wall are notably asymmetric. Between 55°-45°W,the Chasma mouth slopes toward the surrounding terrain. However, theChasma ends mostly as a scarp between 55°-60°W.Benito et al. [2] describe an amphitheater-shaped erosive scarp at85°N, 0°W with orthogonal frontal and southern scarps having a tectonicorigin. In Fig. 1, this scarp would lie near the Chasma source; theredoes not appear to be definite evidence of a scarp with orthogonal sides,nor does this location appear significantly different from other steepsections of the Chasma wall. Similar observations apply to the 2nd describedscarp at 85°N, 17°W. Previously described giant current ripples[2] would lie within the lower left-hand corner of Viking image 560B44on the higher elevations of the floor. The size of these ripples is belowthe resolution of MOLA, but they may be able to be imaged by MOC.Geometry of the Chasma: Six MOLA topographic profiles (fourare shown in Fig. 2) were chosen to represent the general geometry ofthe main section of the Chasma. From Fig. 2, it is evident that the elevationof the Chasma floor varies along the length of the Chasma. TheChasma begins with a U-shaped profile which becomes more V-shaped.The heights of the walls also vary along the length.The distal deposits (Fig. 3a): This image lies mostly within polygonalplains [4]. MOLA track 255 (Fig. 3b) crosses the Chasma wall,defined polygons, and distal scarp. The Chasma wall has a slope ofabout 5°. The polygons form a rough surface at this scale. The polygonsthen slope upward to a smoother region of material probablyslumped from the scarp. The profile then drops off, becoming a scarpwith a slope of about 9°. Below the scarp, the surface is smoother, andbeyond this lie dunes which are not visible in Fig. 3a.DiscussionChasma Boreale exhibits some features similar to those associatedwith terrestrial jökulhlaup events. Single flood events on Earth show avariety of flood conditions, and outburst floods also exhibit several floodpeaks [5] which could explain the irregular nature of the Chasma floor,the discontinuity of terracing, and the non-uniform profile shape. Theasymmetry of the floor at the base of the walls in (Fig. 2 b) could be dueto ice blocks mostly being deposited along the walls as in terrestrialexamples [6]. The non-uniform profile shapes and asymmetries alongthe floor could also be due to sliding and debris avalanching [7]. Theseobservations are in agreement with predictions made by Clifford [1] thatice chunks should result from the flow and later sublime, leaving behindsediment and possible kettles.Terracing could also be explained by the fact that terrestrial tunnelscarved by outflows increase in size with time as the flood level isreaching its maximum value [8]. Terracing would also be expected accordingto Clifford’s [1] prediction that the Chasma would begin smalland enlarge due to frictional melting.The distal deposits may form a debris fan, typical of terrestrialjökulhlaups, in the form of a lobe extending beyond the Chasma mouth.The size of Chasma Boreale (60 km in width) is much larger thanthe typical size (10s-100s m in width) [5, 6, 9] of terrestrial outflowchannels. However, this may be due purely to the scale of the parent icesheets.Benito et al. [2] calculated outflow estimates based on lowerresolutiontopography and used the Manning equation. This calculationmay not be appropriate for a number of reasons. 1) An average channelbed slope is not appropriate for this particular geometry. 2) The hydraulicradius is quite complicated. 3) Observation of terrestrialjökulhlaups has lead to a wide range of velocity models which dependon the amount of sediment in the water [5] which would be difficult toestimate due to the poorly constrained dust/ice ratios for the layereddeposits. 4) The peak outflow discharge of a jökulhlaup depends uponseveral factors such as: volume available for drainage, the stability of theconfining ice to erosion, the geometry of the breach (poorly constrainedwithout accurate topography data), the initiating event, and the height of,in this case, the rim of the crater which held the basal lake [8].The distal deposits present complicated clues to the outflow hypotheses.Several scenarios for their depositional environment couldhave existed, including: 1) deposition under ice, 2) deposition into apossible former body of water [10], and 3) deposition into flat plains.Due to the fact that most of the outwashed sediment came from the erosionof polar layered terrains, it can be assumed that the sediment consistedchiefly of dust [11].Benito et al. [1] observed only one possible example of an esker andattributed the polygons to possible subglacial (or proglacial) braidedchannels. Kargel and Strom [12] do not report any glacially modifiedmorphology in this region.. The dearth of evidence for subglacial activity[12, 2] and the difficulty of searching for evidence in topography ofsmall scale features not seen in Viking images does not tend to pointtoward the first scenario as being likely.In the second scenario, the sediment would be expected to form adeltaic fan. Erosion of a previous delta into the current shape withaysmmetric slopes could then be considered. The erosional processwould have had to form a 1-9° slope on the western side of the depositsand a more gradual slope on the Eastern side.Due to the prevailing wind direction (inferred from local dune orientation)to the southeast [4], asymmetric erosion by wind may havebeen possible. A delta, composed mostly of dust, would have been much
